Professional Acoustic Sound Consulting

Acoustic sound is not just the singing or the sound of the instrument, but also the subtle combination of space, equipment and alignment. A standard acoustic system will bring a close, natural experience, helping the audience feel the full emotion in each melody. However, to build a quality acoustic sound system, users need more than just choosing equipment - it is professional advice, right needs and suitable for the actual space.

In the article below, Phuc Truong Audio will provide you with a comprehensive view of professional acoustic sound consulting, from equipment selection criteria, investment items, design and installation processes, to important notes to optimize performance quality. This is the foundation to help you have a durable, effective and truly inspiring acoustic system.

Factors to Analyze Before Installing an Acoustic Sound System 

To install an Acoustic sound system with maximum efficiency, users need to focus on 4 important factors that determine overall sound quality, frequency reproduction ability and operational stability. 

Analysis of area and shape of performance space

The area and shape of the performance space are the core factors that influence the choice of acoustic system configuration. A compact space (under 20m²) such as a practice room or mini acoustic cafe will only need a small speaker system with moderate power to avoid causing ear-piercing or excessive volume. Meanwhile, an average space of 30-50m² (tea room, lounge) or larger (stage, hall) requires large speaker power, arranging many sound points to ensure the sound covers the entire auditorium.

The shape of the room also determines the placement of equipment. For example, a long, narrow rectangular room often has problems with sound bouncing off the back of the room, while a square space is prone to bass resonance.

The impact of materials and sound absorption in space

Sound does not only come from the speakers but is also strongly influenced by the surrounding materials. Ceilings, walls, floors, glass doors, curtains, carpets and furniture all contribute to the quality of the sound. 

If the room uses too much glass, brick or concrete walls, the sound will easily bounce and echo, making the vocals and instruments become confused and lose detail. On the contrary, rooms with many soft materials such as carpets, sofas, thick curtains will absorb too much sound, making the musical instruments lack brightness and the vocals sound dry.

Proper sound absorption and diffusion solutions are important steps before installation. We often recommend adding sound absorption foam, sound diffuser wood or using reasonably arranged furniture to balance the frequency range. Thanks to that, listeners can clearly feel the separation between guitar, cajon, piano and vocals, instead of hearing "mixed" and confusing. This is the foundation for the equipment system to maximize its capacity and detail.

Determine performance needs to choose the right configuration

Each acoustic performance model has its own sound requirements. For a solo guitar or duet, a compact full-range speaker set, a high-quality microphone, and a compact mixer are enough to fully express the voice and instruments. In contrast, for a full acoustic band (including guitar, bass, cajon, violin, electric piano, etc.), the system needs multiple microphone lines, multiple mixer channels, and even additional monitor speakers so that members can hear each other clearly.

If the needs are not analyzed carefully, the installation can lead to excess equipment (costly, excess capacity) or lack of channels (not enough musical instruments). Phuc Truong Audio often consults according to each specific scenario: small cafe, tea room, outdoor acoustic event or semi-professional art program. This method helps customers have a sufficient system, no waste but still ensures the quality of the performance.

Design and match acoustic equipment system

Once the space and needs have been determined, the next important step is to design and match the system. A basic acoustic system usually includes full-range speakers, a mixer, a microphone, and an amplifier or power amplifier. However, for complex bands, it is necessary to add DI boxes for instruments, monitor speakers for artists, and signal processors (digital reverb, equalizer, compressor) to optimize the sound.

Incorrect power matching or choosing incompatible equipment is a common cause of howling, distortion or rapid equipment failure. Therefore, it is necessary to carefully consider technical parameters such as RMS power, speaker sensitivity, amplifier impedance, and future expansion capabilities. In addition, the installation process must also ensure aesthetics and convenience: neat wiring system, suitable speaker placement, mixer placed in a convenient place for technicians to operate quickly.

Main Categories of Acoustic Sound System

A standard acoustic sound system is not simply a collection of separate devices, but requires close coordination of each item according to the correct technique. The design and implementation process always revolves around the following 4 important items: main speakers, monitor speakers, mixer/digital echo, microphone and accessories.

Main speaker – The heart of the acoustic sound system

The main speaker is the most important component, playing a decisive role in the quality, thickness and spread of the entire system. In acoustic performances, the main speaker needs to fully reproduce all 3 frequency ranges: bass - mid - treble, so that it is both balanced and maintains the simplicity of the instruments and vocals. 

If the bass speaker is not powerful enough, the guitar sound will lose its warmth; if the mid-range speaker is not bright, the singer's voice will be lost in the background music; and if the treble lacks detail, the overall sound will become dry and lacking in emotion. Therefore, choosing the main speaker that is suitable for the space and performance purpose is the first important step.

Monitor Speakers – Tools to help artists keep the beat and emotion

Monitor speakers are often overlooked in basic systems, but are actually extremely important in acoustic performances. Monitors are responsible for providing a direct audio signal to singers and musicians, helping them clearly hear their own performance as well as their teammates on stage. 

Without monitors, artists can easily get “out of tune” or have difficulty controlling their pitch, especially in crowded or echoey spaces. Monitors are usually placed on the stage floor, facing the performers, with a volume just enough to avoid howling. 

In addition, high-end sound systems often use in-ear monitors (personal monitoring headphones), which help artists hear more clearly and limit sound resonance. With the support of monitors, performers can maintain confidence, emotion and harmony throughout the program.

Mixer or digital echo – The brain that controls the entire system

If the speaker is the heart, then the mixer or digital echo is the “brain” of the entire acoustic system. This device is responsible for processing and mixing all audio signals from the microphone, musical instruments to the speaker. With the mixer, the technician can adjust each channel in detail: increase bass for the guitar, brighten treble for the vocals, or add reverb effects to create a natural echo space. 

Meanwhile, modern digital reverbs are also equipped with automatic anti-feedback capabilities, helping vocals stay clear and not screech even when the volume is turned up high. The difference is that analog mixers provide emotional, “raw” sound quality, while digital reverbs allow precise adjustment and preset saving according to each performance space.

Microphones and accessories – Bridges to convey emotions

The microphone is the direct point of contact between the artist and the audience, because it captures vocals and instrument sounds to transmit through the speakers. With acoustic systems, the microphone is often chosen as a condenser to capture details, or a dynamic to prevent feedback and be durable in open spaces. A quality microphone will help each note and each sentence retain clarity, naturalness and emotion. 

In addition to the microphone, accompanying accessories such as microphone stands, signal cables, anti-feedback, sound cards or wireless signal transmission systems also play an important role. They ensure stability, minimize technical risks and bring a seamless experience for both artists and audiences.

With prestige, experience and a source of quality, genuine and diverse products, we are confident in bringing the most satisfaction to customers.

Phuc Truong Audio's services include:

Survey process & actual space assessment

The first step in every acoustic project at Phuc Truong Audio is always a site survey. The technical team will come directly to the construction site to measure the area, ceiling height, wall, floor, ceiling materials and interior materials. 

Every detail is important because it directly affects the reflection and absorption of sound. Then, we simulate with specialized software to evaluate the reverberation status, frequency distribution and determine the location that needs to be treated. The survey results are the scientific basis for providing optimal acoustic treatment solutions, instead of relying solely on intuition like many other small units.

Consulting on acoustic treatment solutions suitable for each need

After the survey results, customers will be recommended appropriate acoustic treatment solutions for each type of space. 

For karaoke rooms, the solution often focuses on sound absorption and anti-feedback; for auditoriums, we focus on the ability to diffuse sound evenly; and for recording studios or home studios, the main goal is to maintain high accuracy in sound reproduction. The materials used are always genuine, meeting safety and aesthetic standards, including: sound-absorbing panels, bass traps, sound-absorbing foam, perforated wood or high-quality acoustic fabrics. 

In particular, we balance technical factors and interior design, helping the space achieve standard sound quality while ensuring aesthetics.

Synchronous construction and installation implementation

Phuc Truong Audio not only stops at consulting but also directly constructs and installs the whole package. All construction processes follow safety standards, from ceiling and wall treatment, to sound wiring and equipment installation. 

We pay special attention to synchronization, meaning that the acoustic system and audio equipment (speakers, amplifiers, digital echo, microphones...) must coordinate smoothly to maximize efficiency. Our team of technicians are all well-trained and have many years of experience in constructing large and small projects, from family karaoke rooms to halls for 500-1000 people.

Check, align & hand over for use

Completing the installation does not mean the job is done. Phuc Truong Audio always has a detailed inspection, adjustment and handover step. The system will be tested at many volume levels, many frequency ranges and many listening angles to ensure consistent sound quality. 

In addition, customers will be guided in detail on how to turn the system on/off, how to control the microphone to avoid howling, how to combine auxiliary equipment. This is the difference of Phuc Truong Audio - we not only sell and install equipment, but also accompany customers for a long time to maximize the value of professional acoustic systems.

Suggestions for Acoustic Sound Systems Suitable for Each Type of Coffee Shop

In sound design for coffee shops, there is no “standard” formula that applies to all. Each type of shop has its own characteristics in terms of space, style and customer base. At Phuc Truong Audio, we often implement according to 3 main suggested processes:

Sound system for small coffee shops – soft background music

For coffee shops with an area of ​​less than 50m², especially "street corner cafe" style shops or take-away shops, the main requirement is to play background music that is just loud enough to hear, not too loud. 

The sound system should be compact, easy to operate but still ensure clear sound quality. Active column speakers or compact wall-mounted speakers are the optimal choice, both saving space and providing even sound coverage. When combined with a basic integrated amplifier and mixer, the owner can easily adjust the background music to suit the intimate, close atmosphere of the restaurant.

Sound system for acoustic coffee shop – medium space

Bars with an area of ​​70-120m², often organizing acoustic in the evening, need a sound system that can meet the background music during the day, but is also "fiery" enough for live performances. Here, 2-way full-range speakers with 25-30cm bass are a popular choice, providing clear vocals, smooth guitar and piano, and neat bass. 

Comes with a power amplifier and anti-feedback digital echo, helping to ensure the singer's voice is not overwhelmed by the musical instruments. Combined with a high-quality wireless microphone, this system creates professionalism, bringing an experience similar to a tea room but still maintaining the friendliness of a coffee shop.

Sound system for garden cafe - large space

For large garden cafes, the demand is often for organizing mini shows, birthday events, and large gatherings. At this time, a sound system with more powerful capacity, wide coverage while still maintaining warmth is needed. 

30-40cm full bass speakers, combined with monitoring speakers for singers and musicians is the ideal solution. In addition, a powered or acoustic subwoofer is also needed to increase the strength of the bass range, creating balance when singing live. For the system to operate, we often advise adding a multi-line mixer (12-16 lines) to meet the needs of enough microphones and musical instruments.

Sound system for coffee shops and tea rooms - professional style

This is a high-end segment, often serving customers who love quality live music, requiring performance-standard sound. The system should include high-power full-range speakers, dual subwoofers, condenser microphones for vocals, and a digital mixer for detailed sound processing. 

Not only stopping at background music or acoustic, this sound system must also perform well the band's performances, helping the singer control his voice at every range. In addition, the stage lighting system is also synchronized to create a professional space, turning the bar into a real cultural and musical meeting place.

Frequently Asked Questions about Acoustic Sound

Should I use a karaoke amplifier for an acoustic system?

Karaoke amplifier modern, especially 3-in-1 digital amplifiers, often integrate both digital reverb and wireless microphones, very convenient for family karaoke systemHowever, with live acoustics with many instruments, karaoke amplifiers may be limited in the number of lines. In this case, customers should combine karaoke amplifiers for vocals + mix for the instrument to achieve optimal performance.

Is karaoke microphone suitable for acoustic singing?

Karaoke microphones are usually dynamic microphones, with the advantage of being good at preventing howling, easy to use, and suitable for rooms with speakers placed near the microphone. Meanwhile, professional acoustic microphones (condenser) record more details but are prone to howling and require a technician to control. Therefore, many small acoustic tea rooms often prioritize high-quality wireless karaoke microphones such as CAVS S4 Wireless Microphone or KTreasure GS600 - both keeping the rustic feel and limiting howling.

Does an acoustic system need a digital reverb like karaoke?

Acoustic is more natural so it doesn't need too much echo, but still needs a light reverb for natural vocals. Echo number modern (eg EUDAC KM-400) can customize echo and reverb separately, allowing quick switching between acoustic mode (high reverb, low echo) and karaoke mode (clear echo, medium reverb). This is a highly appreciated solution because it brings flexibility to multi-purpose spaces.

Is the wireless karaoke microphone stable when used for acoustic live?

Yes, if you choose a quality microphone. High-end wireless microphones such as KTreasure GS600 or CAVS S4 have good voice capture, low interference, and anti-feedback. When used for live acoustics, wireless microphones also help singers move and express themselves more freely, instead of being limited by wires.
