Experience in Choosing Sound Systems for Classrooms and Classrooms

One sound system Quality is not only a teaching aid but also a key factor in creating an effective and engaging learning environment. Clear and easy-to-hear sound helps students concentrate better, absorb lessons better and participate actively in classroom activities.

In this article, we'll dive into the important factors to consider when choosing speakers and setting up a classroom sound system, with real-world data and specific examples to illustrate.

Factors to Consider When Choosing a Sound System for Schools and Classrooms

Room size and acoustics

The size of the classroom directly affects the required speaker power. According to research from the International Acoustics Association, every 10m² of room area requires about 10W of speaker power to ensure the sound is emitted evenly.

• Small room (under 20m²): Need speakers with power from 30W to 50W.
• Medium room (20-50m²): Need speakers with power from 60W to 100W.
• Large room (over 50m²): Requires speakers with a capacity of 100W or more.

The materials in the room also play a role. Hard surfaces like concrete or tile will reflect sound strongly, causing echoes, while soft surfaces like curtains and carpets will absorb sound.

A study by the College of Music found that using sound-absorbing materials can reduce reverberation by up to 50%, improving the sound quality in the classroom.

Uses

Classroom sound systems can serve many different purposes such as teaching, presenting, showing movies or listening to music. Each purpose will have different requirements for sound quality:

• Teaching: High clarity is required, focusing on the speech frequency range (approximately 300Hz to 3kHz).
• Listening to music: Need realistic and detailed sound, require wider frequency range (from 20Hz to 20kHz).

According to a survey from an international education organization, 70% of teachers believe that good sound systems help improve students' learning ability.

Budget

Budget is an essential factor when choosing a sound system. Sound systems come in a variety of price ranges:

Determining your budget in advance will help you find a system that fits your needs and budget.

Components of a Classroom Sound System

LoA

LoA is the main component in the sound system. There are three common types of speakers:

• Ceiling speakers: Suitable for classrooms with false ceilings, neat and aesthetic design. For example: Toa F-1000BT ceiling speaker (reference price: 2.000.000 VND) provides good sound quality for small spaces.
• Wall mounted speakers: Suitable for all types of ceilings and easy to install. For example, the Bose DesignMax DM2C-LP wall-mounted speaker (reference price: VND 4.500.000) provides a great music listening experience in the classroom.
• Portable speaker: Flexible and easy to move, suitable for outdoor activities. For example: JBL PartyBox 110 portable speaker (reference price: 9.000.000 VND) is very suitable for extracurricular events.

It is necessary to choose speakers with appropriate capacity for the classroom area and appropriate speaker placement to ensure sound coverage.

Amplifier

Amplifier has the role of amplifying the audio signal from the source (computer, microphone...) to the speaker. Choosing an amplifier with the right capacity for the speaker and necessary features such as volume, bass and treble adjustment is very important. For example: Toa A-2120 Amplifier (reference price: 3.000.000 VND) is a good choice for many types of classrooms.

Microphone

Microphone is also an indispensable part of the classroom sound system:

• Wireless microphones: Convenient for teachers to move around the classroom. For example: Shure BLX288/PG58 wireless microphone (reference price: 7.000.000 VND) helps teachers freely interact with students.
• Lapel microphone: Helps teachers free their hands and provide clearer sound. For example, the Rode smartLav+ Lavalier Microphone (reference price: 1.500.000 VND) is very suitable for online lectures.
• Handheld microphone: Suitable for speaking or presentation activities. For example: Shure SM58 handheld microphone (reference price: 3.000.000 VND) is widely used in large events.

Other ingredients

In addition to the main devices, you also need to consider a mixer to connect different sound sources such as microphones, computers or musical instruments.

Tips for Optimizing Classroom Sound

To optimize sound quality in the classroom, you should:

• Acoustic treatment: Use curtains, carpets or soundproofing foam to reduce echoes and noise.
• Reasonable equipment layout: Place the speaker in a high position, facing the students and avoid placing it near walls or corners of the room.
• Regular maintenance: Clean the speakers and microphones periodically and check the connections to ensure the system is always working properly.

A study by the Institute of Acoustic Research found that proper acoustic treatment can improve speech clarity by up to 30%, helping to improve teaching effectiveness.

New Technology In Classroom Sound Systems

New technologies being applied in classroom sound systems include:

• Voice amplification system: Helps teachers speak louder and clearer without much effort.
• Surround sound system: Creates vivid and realistic sound effects, enhancing the listening experience for students.
• Integrate with online learning platforms: Connect with Zoom or Google Meet to enhance your remote learning experience.

According to a report by the international education organization UNESCO, the application of technology in teaching has increased student participation rates by up to 40%, especially during the COVID-19 pandemic.

Audio Solutions For Classrooms

Depending on the size of the classroom, you should choose the appropriate solution:

 Investing in a quality sound system is essential to creating the best learning environment for students. A recent study found that a good learning environment can increase knowledge retention by up to 60%, further confirming the importance of choosing the right sound system in modern education.

Hopefully this article has provided you with useful information to choose speakers and set up the right sound system for your classroom.

FAQ – Frequently asked questions when installing sound systems for schools and classrooms

1. What audio technologies are currently popular in education?

Modern audio technology includes voice amplification, surround sound, and wireless microphones. These technologies improve sound quality and enhance the learning experience. According to a UNESCO report, the use of technology in teaching has increased student participation rates by up to 40%.

2. How to install a sound system effectively?

Installing an effective sound system involves determining the appropriate speaker location, ensuring that the speakers are facing the students and avoiding placement near walls or corners of the room. Speakers should be installed at a height of 2 to 3 meters to optimize sound coverage.

3. How does sound affect learning performance?

Research shows that a good acoustic environment can increase knowledge retention by up to 60%. Clear sound helps students focus better and absorb information more effectively.
