The 9 Best Voice Amplifiers for Teachers to Be Heard in Any Size Classroom and Outdoors

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 these issues, you might want to consider voice amplifiers for your classroom. These devices are becoming increasingly popular for making sure your students can hear you loud and clear, but as a teacher it can be daunting to try and purchase a new device.

Discover the 9 Best Voice Amplifiers for Teachers

You know, during the pandemic we do need these tiny helpers to speak wearing a mask and ensure the safety of our students.

I know how difficult it can be to research technology for the classroom from personal experience, so I wanted to create an ultimate guide on the voice amplifiers for educators with everything you need to know aboutthem.

After reading this article, you will know all about:

How to Choose a Voice Amplifier

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

4 Criteria for Choosing a Voice Amplifier
CriterionDescription
As a rule of thumb, a battery capacity of 1500 or more is considered good for this gadget. It gives approximately 6-8 hours of continuous working time. The amplifier with the 1800mA battery will work for about 10-12 hours without charging.

The NORWAY gadget has the most powerful battery among models in my list, it can work up to 38 hours without recharging.

A full charge usually takes 3 to 5 hours.

2. Bluetooth vs WiredIf you prefer to roam freely around the room without any restrictions, then bluetooth is a great option for connecting your microphone to speakers. You can place them anywhere in the middle or back of the space and still have no issue with sound quality – giving yourself as much freedom as possible while teaching.

Alternatively, wires provide an added degree of reliability when it comes to maintaining connection so that may be better suited if necessary!

3. Ease Of UseIf teaching with your hands comes easier than through words alone, look out for an option that offers a convenient wireless device so everything can be done at once. For example, WinBridge WB001 comes with a convenient waistband so you can attach it to your body and move around the classroom.

For those hoping to take their amp outdoors on adventures, make sure it is waterproofed — otherwise a rainy day could spell disaster!

Take a minute to consider when and where you will use your amp.

If you’re teaching outdoors or to a large lecture hall, you might want to look into getting an amplifier with a large range. For example, the MAONO model — it has 800 sq.m sound coverage, while the Giecy modelcover about 20000 sq.ft (1000 sq.m).

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

Before presenting you my top-list, I’d like to to focus your attention on the three models that I liked the most.
