As in-person teaching resumes, the need for a voice amplifier for teachers has become increasingly evident. Many educators are experiencing strained voices due to the challenge of being heard in larger classrooms, a consequence of budget cuts in numerous school districts. Additionally, the use of face masks in classrooms further muffles teachers’ voices, underscoring the necessity for such amplification devices.
If you’ve been experiencing these issues, it’s worth considering incorporating voice amplifiers in your classroom setup. Especially during the pandemic, these small yet significant devices have become essential tools to aid in speaking clearly while wearing a mask, thereby ensuring the safety and understanding of our students.
Just ordered a voice amplifier for school. One day of over-projecting my voice through a mask is enough for me! I reckon they are going to be an essential for every teacher before long #edchatie

What Is a Voice Amplifier?
A voice amplifier is a device that helps to increase the loudness of a person’s speaking voice. It is also known as a personal amplifier, PA system, or sound amplification system. They come in both handheld and wearable designs, with the former being ideal for those who need to move around the classroom while speaking.
There are a few different styles of microphones for personal voice amplifiers. Some come with a small, handheld microphone. Others have headsets, which include a microphone that is mounted in front of the mouth. There is also a style known as the collar microphone which circles the neck like a necklace.
The key to using an amplifier correctly and ensuring a clear sound is to set it up correctly. Depending on the type of amp, you can position it on a headset microphone, an earpiece, or as a clip. The microphone should be between 1 to 3 cm from the mouth to avoid feedback. Any crackling noises may indicate that it is not connected properly. It can also be worn around your waist, your neck, or positioned on a chair or wheelchair.
If you want to learn more about this, read our article, where we talk in detail about what a voice amplifier is.
How to Choose a Voice Amplifier
Before we get into the list I have compiled on the voice amplifiers for teachers, it’s important to know what you’re looking for. Here are some of the criteria to pay attention to when choosing a new device.
| Criterion | Description |
| As a rule of thumb, a battery capacity of 1500 or more is considered good for this gadget. It gives approximately 6-8 hours of continuous working time. The amplifier with the 1800mA battery will work for about 10-12 hours without charging. The NORWAY gadget has the most powerful battery among models in my list, it can work up to 38 hours without recharging. A full charge usually takes 3 to 5 hours. | |
| 2. Bluetooth vs Wired | In a Bluetooth (or wireless) amp, the microphone and the speaker connect via Bluetooth, meaning that you can place the speaker closer to the students, or in the middle of the room and speak at your normal volume. Unfortunately, a wireless device is easy to run out of power needs frequent charging, and is tedious to use. Alternatively, wires provide an added degree of reliability when it comes to maintaining connection so that may be better suited if necessary. Plus, the operation is straightforward, even without checking the manual. Just plug and play. You determine what is a priority for you. |
| 3. Ease Of Use | If teaching with your hands comes easier than through words alone, look out for an option that offers a convenient wireless device so everything can be done at once. For example, WinBridge WB001 comes with a convenient waistband so you can attach it to your body and move around the classroom. For those hoping to take their amp outdoors on adventures, make sure it is waterproofed — otherwise, a rainy day could spell disaster! |
| Take a minute to consider when and where you will use your amp. If you’re teaching outdoors or in a large lecture hall, you might want to look into getting an amplifier with a large range. For example, the MAONO model — has 800 sq.m sound coverage, while the Giecy model covers about 20000 sq. ft (1000 sq.m). | |
| As a rule, the price does not depend much on the characteristics of the gadget, most amplifiers are approximately the same — about $30. The WinBridge models are in the higher price range, but, as the reviews show, they are quite durable. The budget of my guide ranges from US$20 to US$140, so you can buy the most cost-effective voice amplifier for teachers. |
Sometimes as teachers, we don’t even realize how noisy our classrooms can get. Check out the below video if you want to hear some examples of loud classrooms that could benefit from a voice amplification system.

F.A.Q.
We have tried to answer frequently asked questions that you may have when choosing an amplifier.
What is the optimal power for an amplifier?
As a kindergarten teacher, you want to ensure that your students are able to clearly understand the material being taught. That's why our recommended amplifier has an output power of 5-10W - perfect for classes with 30-80 children! With this type of voice amplifier, kindergartens everywhere can benefit from its optimal sound quality and reach all their little learners effectively.
Our advice to primary and secondary school teachers? Invest in 10-18W voice amplifiers - the perfect choice for classrooms with 80-120 students! Not only does this power range match what's typically found in schools, but it also provides an effective amplification solution.
Teaching large classrooms? With just one of our 20W+ voice amplifiers, you can ensure every student in your 180-person class is hearing each lesson loud and clear. Make sure everyone gets the most out of lecture time with a powerful sound system!
What amplifier do you recommend for teaching outdoors?
For outdoor teaching, our most recommended is a fall-proof, waterproof, and dustproof voice amplifier.
How can I make my lessons interactive with a voice amp?
A voice amplifier allows teachers to seamlessly collaborate with students. Connect the device up to two wireless mics and leverage it for interactive lectures or Q&A sessions — fostering collaboration between teacher and student in an engaging way.
How to choose an amplifier if I need to wear a mask?
Yes, the Covid19 pandemic has created a new challenge for teachers teaching in classrooms — the use of masks to protect everyone's safety. In order to deliver instruction effectively, we recommend that these educators employ high-powered loudspeakers with an output power of at least 20W. Not only will this help ensure students can clearly hear their teacher from distances up to 1,000 square feet, but it also allows them to reach up to 180 people simultaneously.

Hi! How can I connect a wireless microphone to a wireless Bluetooth speaker to be used as a voice amplifier? What are some suggestions of products? This is for an outdoor class.
To get the clearest sound quality possible, you need a laptop with Bluetooth capabilities and an external microphone connected to its mic input. This simple setup will ensure professional-level audio for your next project.
Are you in the market for a top-notch wearable voice amplifier that can effectively project your speaking and singing to audiences of 25 to 75 people? If so, I’m looking for advice.
Recently, I have been using Winbridge amplifiers but their sound quality falls short and produces an unpleasant “squeaking” when the microphone gets near the speaker if bending down or moving around. Is there a better alternative available on the market within my price range ($40) OR should I be prepared to invest more in order get superior performance and audio clarity?
Any feedback would be greatly appreciated!
To prevent feedback, consider swapping the microphone for a WinBridge model with Bluetooth headset to allow more freedom of movement.
