Best Classroom Microphone System – Top 5 Picks

Since clarity is what you need and not necessarily volume, a good speaker and a wireless mic may be the best option. Together they make up a microphone system that is another way to protect your voice in the classroom while making sure everyone hears you.

A small portable amplifier may be all you need to talk to a small class of elementary school students, but if you need to speak in a large room and want very clear audio, then you should consider a wireless microphone that works with a high-quality speaker.

Several of the following speakers can be calibrated specifically for lessons and outdoor recreation. Some of them allow you to stream music or lectures from radio stations or online.

The speakers can be placed anywhere in the room within the given range with these best microphones for teachers. Since 75 percent of education is listening, it’s important that they not only hear the sound but also the intonation and subtleties of your voice to better understand what you are talking about.

This mic can be dropped, tossed, kicked, and slid across the floor of the classroom without damaging the high-quality mic inside.

When voice problems occur, your teaching may become sub-standard. Teachers do things to make up for not being able to speak. It’s called presenteeism rather than absenteeism. You are at work, but not functioning on all cylinders. One of your most important tools is missing: your voice.

I did some research and found this article, which explains that the main problem is volume. I recommend you read it to get an idea of how serious the problem is. It concludes that amplification is the solution. Many voice disorders can be avoided or reduced if the teacher doesn’t have to speak loudly (read “yell”) most of the day.

Voice amplifiers to the rescue. They’re great when your voice is tired but you still have a lot of speaking to do before the day is done. If you’ve tapped out your voice for the day or week, a voice amplifier will allow a soft voice to be heard, even by a large group.

Amplifiers are essential for a major event or assembly. Just plug in the headset, and clip the unit to your belt or waistband and turn it on. If you support my idea of giving your voice a break, check out my detailed reviews of the best voice amplifiers for teachers.

How Amplifiers Work

Also called a speech assistance device, a portable voice amplifier is a mini public address system you can clip on your belt or wear around your neck. They’re relatively small units but provide a lot of volume when you need to speak to a large group at an outdoor event or even in an indoor assembly where the whole gym is full of students and teachers.

The small amplifier has a built-in speaker and a lightweight, portable headset. Some headsets are wired and some are wireless. If you need more amplification, you can download amplification apps for Android and iPhone. The sets come with a rechargeable lithium battery and can be operated with one hand.

Yes, my friends, I said one hand.

You can hold your clipboard, beverage, program, speech, or anything else you need in your other hand. Just plug in the headset and start talking. Use your normal voice and the people in the back of a large, crowded room will hear you. Take a look at this to get an idea of the possibilities.

This video doesn’t have a huge classroom, but the teacher doesn’t need to strain at all and all the kids can hear clearly no matter where they’re sitting or where the teacher is walking.

Different Kinds Of Amplifiers

There’s a big variety of voice amplifiers on the market that may be useful for teachers. Below, I’ve given you a list of the seven best voice amplifiers for teachers so you can get an idea of what’s available. The choice you make will depend on your usage.

For example, will you use it in a regular classroom, a large assembly hall, outdoors, or all of the above? Do you want to be able to play music or discussions you’ve downloaded?

I have given you a few of the devices I believe give high-quality voice amplification for the classroom. Using these devices is highly recommended for saving your voice as well as enhancing the learning experience for your students. If you primarily teach virtually, then one of the options for the best microphones for online teaching will be more applicable to your needs.

You can use amplifiers in conjunction with a variety of speakers. Check out the following article to learn more about classroom computer speakers that will make your teaching days easier on your voice.

4 Steps To Choosing The Best Voice Amplifier

Portable voice amplifiers for teachers have many features that will help teachers save their voices. The basic features that all of them have are a microphone, speaker, and powered amplifier. These are distinct from the best voice recorders for lectures, which specifically record sound instead of merely amplifying it.

They have volume control, and most of them come with a method to wear the device. Before choosing one that seems to suit your needs, I recommend you consider the features mentioned below.

Step 1. Start With The Battery

The first thing to look at is how long the battery lasts. Some batteries need to be charged every few hours, and some have instructions that the battery should be charged only when it’s completely dead. Also, some batteries last three hours, and some last 15 hours.

If you’re a music teacher or a physical education teacher, you may need a long-lasting battery so you only have to charge it at night. If you’re using the voice amplifier on an all-day field trip, the longer-lasting battery may be essential.

However, if you have time during the day to keep your device plugged in, a short-term battery may be enough for you.

Step 2. Consider Strength Or Volume

A voice amplifier is only useful if it helps people at a distance hear you when you speak in a normal voice. Before choosing a device, check the amount of area it covers with clear sound. Some cover 10,000 square feet and are suitable for outdoors, and some cover 5,000 square feet and are suitable for a medium-size classroom.

As you saw in the video above, the classroom wasn’t very large, but the amplifier made a big difference when the teacher walked around the room. If that’s all you need, you don’t have to spend a lot on one that fills a whole gymnasium with sound.

Step 3. Pay Attention To Portability

All of the devices I recommended are portable. This is a very important feature for a teacher, whether in a classroom or outdoors. If you’re just giving a lecture, you’ll probably have a sound system and stand at a lectern, but for most of us, movement is important while we talk to our students.

The above-mentioned devices are small, lightweight, and can be worn around your neck or clipped to your belt. Don’t forget that portability and batteries go together.

Step 4. Find An Amplifier That’s Easy To Use

We may vary in our understanding of technology, and some voice amplifiers have different features and connections.

If you want one that has all the bells and whistles, make sure you take the time to read the instruction booklet or find someone to explain it to you so you can actually use the features you paid for. For example, if you want to play music in the background while you speak on a certain subject, you need to know how to set it up for that.

If you plan to use your voice amplification system outdoors most of the time, you may want to consider the waterproof feature.

Then you don’t have to worry about protecting it if it starts to rain or the air becomes very moist and humid. A wireless voice amplifier for teachers can be your best option if you prefer to be hands-free.

Finally, make sure your amplifier is comfortable to wear around your waist or neck for long periods. The lightweight devices tend to be the most comfortable.

Tips On How To Use A Voice Amplifier

As teachers, we’re always trying to get the attention of our students. Many times, they stop listening because they can’t hear what’s being said and can’t follow. To remedy this, we start to speak loudly and even shout in some cases. When you use a voice amplifier, this is the first thing you need to stop. You can speak in a normal, even quiet, voice and still be heard at the back of the gym.

Another tip that will help the voice amplifier be more effective is for you to speak slowly.

If you teach at the primary level, you may already know how effective this is to help children to follow, but if you teach teenagers, you may have developed the habit of speaking fast in the hope that it’ll better hold their attention.

The voice amplifier allows people at a distance to hear you speak, even though they can’t see you up close. When you speak more slowly, people at a distance may be able to follow better.

In this video, you can see how a voice amplifier for teachers is being used and reviewed. Two of the products she discusses are on my list of the best voice amplifier for teachers:

You’ve reached this part! I hope this microphone system and voice amplifier review of ours has helped you find the one that is right for you. We have already chosen our top favorite; it’s your time now to tell us what’s yours and why!

But before that… if you’re also thinking of recording your lectures, you need the best classroom camera for best results.

Our Final Thoughts

Whether you teach physical education or a small kindergarten class, a portable voice amplifier will improve your quality of teaching while protecting your health.

There’s a large selection of features for every need, from the smallest classroom to the playing field, but the GIGAPHONE G100 made it to the top of my list because it has everything that I need to amplify my voice and it is also very convenient for me to carry it around.

If you can’t find a wireless one that gives enough volume for your needs, make sure it can be connected to another device such as computer speakers. To learn about the best computer speakers on the market, see my other blog post.

The name says it all. This amplifier will produce clear sound in a gym and even outdoors. It is easy to use hands-free with both a waist belt and shoulder strap. It weighs less than a pound and has a solid body that protects the mechanism from drops, shocks, dust, and moisture. It takes about three hours for a 12-hour charge.
