How Voice Amplifiers are Beneficial for Teachers in 2021

Voice amplifiers, sometimes referred to as loudspeakers, are quickly becoming staples in the classroom, especially as more and more teachers are required to wear masks while teaching. Many teachers are finding that even without masks, voice amplifiers help them teach in their classrooms due to their ability to help students hear their lessons as well. Keep reading to find out why voice amplifiers are beneficial in the classroom as well as a few models that are worth their weight in gold for teachers looking to reach more of their students than ever before.


There are far too many benefits to using a voice amplifier, so we thought we would break down our top four reasons that teachers should utilize a voice amplifier in the classroom.

Less Stress

We’ve all spent time nearly yelling at our students in an attempt to get them to listen, only to find that by the time we’re home for the day, our voices are lost. With a voice amplifier, teachers are able to speak the same amount that they normally would without putting undue stress on their vocal cords. This is definitely one of those situations where an ounce of prevention is worth a pound of treatment, with many teachers finding they need to treat their vocal cords later in life due to the years of projecting their voices in the classroom.

Idealized Learning Environment

Besides less stress on the body, voice amplifiers also allow teachers to have less stress in the classroom by creating an idealized learning environment that simply cannot be beaten. Instead of facilitating a loud, chaotic classroom, voice amplifiers allow teachers to be in full control of their classrooms. No longer do teachers need to worry about whether or not their students can hear them, nor will teachers add to classroom noise that many students can find distracting.

Reach All Students

With some students attempting to listen to their teacher while others are talking over, voice amplifiers allow all students to hear exactly what’s being said by their instructors. This creates a quieter learning environment that actually makes teaching much easier as well as allowing more students to learn. For example, many students who sit in the back don’t always hear exactly what is being said by their teacher due to the rows of students sitting in front of them who can be disruptive. With a voice amplifier, teachers don’t need to worry about reaching those students at all.

Loud and Clear

Finally, voice amplifiers allow your students to hear you loud and clear, especially as more and more schools require education professionals to wear a mask while they are teaching. With a voice amplifier, teachers no longer need to worry about sounding muffled or not having their students fully understand what they are saying by providing loud, clear sound for everyone in the classroom. If that’s not a win-win for everyone, we don’t know what is.


There are several different vocal amplifier systems available to teachers, but the following models are our absolute top picks for those looking to purchase a system.

HamiltonBuhl Amp-Up! Personal UHF Voice Amplifier with Wireless Microphone

HamiltonBuhl Amp-Up! Personal UHF Voice Amplifier with Wireless Microphone

This is our top pick for a few reasons, namely that it’s portable and can be used wherever teachers go. This system allows teachers to clearly, crisply, and loudly speak to their students, whether they’re in the classroom, on a field trip, or in an assembly. The 25W output covers large areas while the long battery life ensures students are able to communicate with their students all day long. Users are able to easily adjust the sound settings to ensure volume levels are correct, and thanks to the Bluetooth technology, USB/TF card slot and AUX-IN built into the device, users can play other audio through the device as well. Finally, the wireless, head-worn microphone and waistband hook allow users to use this device wherever they are, bringing forth a whole new level of unmatched portability.

Avid Education PA-216 35 Watt Portable PA Amplifier

AVID Education PA-216 35 Watt Portable PA Amplifier

This system isn’t the most portable on our list, but it’s perfect for those looking to reach a large audience outside or in bigger rooms like playgrounds, field trip locations, assembly halls, etc. The shoulder strap and handle allow users to easily move this system where they need it while the 35-Watt system means it’s loud while providing clear, crisp sound for those who need to hear it. Unlike some of the other systems on our list, this one only has a USB port; however, the sound quality and portability make it a must for those who need to regularly speak in large areas.

Avid Education PA-122 6 Watt PA Waistband Amplifier

AVID Education PA-122 6 Watt PA Waistband Amplifier

This system may be small, but it packs a powerful punch for those who need to use a voice amplifier in a classroom setting. While this system is incredibly basic (it’s not going to record nor does it have plug-ins for outside audio to playback), it’s perfect for those who feel they only need to amplify their voices. Due to its smaller size, users can’t really rely on this one outside of the classroom.

There is a multitude of reasons to purchase a voice amplifier, including creating a more ideal learning environment and putting less stress on educators’ bodies. Purchase a voice amplifier today and experience the difference in your teaching as soon as possible.
