Discover the 13 Best Voice Amplifiers for Teachers you can Use in the Classroom and at Home!

As in-person teaching becomes more common again, many teachers are finding that they are straining their voices trying to be heard in the classroom. Budget cuts in many school districts have led to increased classroom size, and the use of face masks in the classroom can cause teachers’ voices to be muffled. If you’ve been having any of these issues, you might want to consider voice amplifiers for your classroom.

What is a Voice Amplifier and When Can You Use It?

Before we get into our ultimate guide on the best voice amplifiers for teachers, we should go over what exactly a voice amplifier is and when you can use it. While some people might think voice amplifiers and microphones are one in the same, they aren’t. Microphones are often a component of voice amplification systems, but voice amplifiers in general are their own type of device.

In a classroom, voice amplification technology usually works by connecting a wireless microphone worn somewhere on the teacher’s person with speakers throughout the classroom. This type of technology can be installed in virtually any type of classroom, large or small.

While most people might assume that voice amplification devices or speech support devices should only be used in a large lecture setting, that’s simply not the case. In modern teaching, especially with face masking and students with varying hearing abilities, voice amplification can be a fantastic accommodation in a classroom of any size.

With the return to in-person teaching and many teachers wearing a mask in the classroom, voice amplification is more important than ever. If you want to see more info about which voice amplifiers work best with masks, check out the YouTube video above.

3 Benefits of Using a Voice Amplifier in Lessons

So what does the use of these super devices in the classroom give us, teachers? Let’s figure it out.

1. Background Noise and Bad Acoustics in the Classroom

One of the major benefits of using a voice amplifier in the classroom is that it can help counteract background noise and bad acoustics in the classroom. In many school classrooms, materials used in construction have fostered a poor acoustic environment. Combine this with a noisy classroom and it can be very hard for students to hear the lesson. Using a voice amplifier is a great solution for this!

Use voice amplifiers in online and offline classes

2. Hearing Loss in Students

Another reason that you might want to consider using a voice amplifier in your classroom is that hearing loss in students is much more common than one might think. It’s estimated that 14.9% of school children in the U.S. experience some level of hearing loss. By using a voice amplification system in your classroom, you can help students who might have otherwise had a hard time hearing the lesson.

Your speech will stand out clearly among extraneous sounds

3. It Helps You Focus on Teaching

The next benefit of using voice amplification in the classroom is that it helps you focus on what’s important: the lesson and your students. Every minute you spend worrying about being heard or focusing on being loud enough for your students is a minute that could have been spent with greater focus on the teaching at hand. If you find yourself getting a sore throat from raising your voice as a teacher, voice amplification might be for you.

This is especially useful for large classes

If you want a quick overview of the benefits of using a voice amplifier in the classroom, check out this short YouTube video. This video goes over the ways you can protect your voice in the classroom with voice amplification:

Another device that can have great benefits when used in lessons is a document camera. Check out our list of the best document cameras for teachers here!

How to Choose a Voice Amplifier – An Ultimate Guide

Before we get into the list I have compiled on the best 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.

1. Battery Life

Some voice amplifiers have great capabilities but can’t last through a full workday without being charged. Consider how long you will be teaching with an amplifier daily and ensure the device you purchase can accommodate.

Choose a model depending on the number of lessons per day

2. Bluetooth vs Wired Microphone

Consider whether you would prefer to use a wireless microphone or if you’re fine with your headset being connected to a wire. If you prefer to move around the classroom without having the amplifier attached to a neck or waistband, think about investing in a Bluetooth microphone.

It all depends on how convenient it is for you

3. Budget

Of course, price range is always important to consider when purchasing new classroom materials. Thankfully, the list we have below of voice amplifiers has options to accommodate a wide range of budgets.

Remember: expensive does not always mean good

4. Class and Classroom Size

Take a minute to consider your class and classroom size. If you’re teaching in a small classroom to a small number of people, you can probably get away with having a less powerful device. If you’re teaching outdoors or to a large lecture hall, you might want to look into getting an amplifier with a large range.

Sometimes as teachers we don’t even realize how noisy our classrooms can get. Check out the above video if you want to hear some examples of loud classrooms that could benefit from a voice amplification system.

The Best Voice Amplifiers for Teachers

Now that we’ve gone over what a voice amplifier is and discussed the benefits of using one in lessons, let’s get into the best voice amplifiers for teachers.
