The 10 Best Voice Amplifiers for Teachers

By Editorial Staff •  Updated: 08/29/23 •  Teaching Tools

Voice amplifiers are essential for any large classroom, field trip, auditorium, or teacher who wants a solution to less yelling. While non-teachers think being an educator is “easy” because you only teach 3-5 hours a day, we know that kind of class load is equivalent to a 3-5 hour speech every day, which can be exhausting.

This is where a voice amplifier comes in handy. It helps you not get so tired from talking all day, allows students to hear you more efficiently, and is incredibly helpful when feeling sick.

The surprising benefits of using an amplifier for your voice

In short, you’ll be more effective in the classroom. Not only will you get less tired from constantly raising your voice to give instructions, but you’ll also be in a better mood and have more energy for your final classes at the end of the day.

In addition, students will be able to hear you more easily. This is an obvious benefit, but when you have a voice amplifier, you can overtalk a noisy classroom to maintain control and have students understand the required instructions to complete the lesson objectives.

Last is for those days when you’re sick. We’ve all been there; you have a sore throat and are not in the mood to teach and manage a class. As a teacher, you have to push through; a voice amplifier helps with this.

What to look for in an amplifier?

Battery life, the microphone setup, the ability to use an external mic, and the audio quality are all things we consider when looking for the ideal voice amplifier for teaching. Some amplifiers are more geared for vocals; others can also be used for music.

Price does play a role, too as well. Depending on the size of your class and the features you need will determine the price point you look at. Most teachers will be OK with any budget to mid-range voice amplifier.

Using a voice amplifier with a mask

If you’re curious how to best use a voice amplifier with a mask, it works best to put the headset and microphone combination on first and then put your show over the microphone. This way, your voice sounds clear, though it does take time to get used to as the mask pushes the microphone almost into your mouth.

You can wear the microphone over the mask but your voice will sound a bit muffled and unclear. So if you’re looking to get the best audio then wear your mask over the microphone.

Additional tips for voice amplification

Poor posture, breathing methods and vocal capacity can influence your voice’s capacity to speak and project in a classroom. If you have an issue amplifying your voice in the classroom here are some helpful tips:

Breathing techniques

To achieve the projection you desire, it is critical to understand how to utilize breathing methods. Understanding how to breathe and vocalize from your diaphragm can really assist you in gaining power in your voice.

When people use their diaphragm to breathe, it’s far easier to control the breath. When you exhale deeply, your diaphragm rises and helps make your voice louder, more confident, and more compelling.

Vocal ability

When you’re going to speak for a long time, it’s critical to warm up your vocal chords. Whether you’re speaking in front of others, teaching a class, or simply informing others it’s smart to warm up your voice and be prepare it for intensive usage. If you don’t warm up your vocal chords, you proverbially “loose” your voice.

Humming, lip trills (the noise you’d make if you were imitating the sound of a toy car or aircraft), and breathing workouts can all help relax your vocal cords and prepare them for hours of teaching.

Then when ready, enhance your voice from within your diaphragm by opening up your mouth and throat while vocalizing loudly. These procedures and exercises will help you sound your best while speaking during the time you are performing.
