Voice amplifiers are essential for any large classroom, field trip, auditorium or any teacher who wants a solution to less yelling. While non-teachers think being an educator is “easy” in that you only teach 3-5 hours a day, we know that kind of class load is equivalent to a 3-5 hour speech each and everyday which can be quite 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 easily and is incredibly helpful on those days where you’re feeling a bit sick.
The surprising benefits of using an amplifier for your voice
In short, you’ll simply be more effective in the classroom. Not only will you get less tired from having to constantly raise your voice to give instructions, you’ll 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 over talk a noisy classroom to maintain control as well as 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 just not in the mood for teaching and managing a class. As a teacher you have to push through and a voice amplifier helps with this.
What to look for in an amplifier?
Battery life, the microphone setup and the ability to use an external mic as well as the audio quality are all things we took into consideration when looking for the ideal setup for teaching. Some amplifiers are more gear for vocals, others can be used for music as well.
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 fine with any budget to mid-range voice amplifier.
Using a voice amplifier with a mask
If you’re curious about how to best use a voice amplifier with a mask, from what we’ve test it works best to put the headset and microphone combination on first and to then put your mask over the microphone. This way your voice sounds clear, though it does take time getting 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:
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.
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.
