Best Voice Amplifier for Teachers With Long Battery Life

Speaking in front of a large crowd of people can be challenging enough without having to worry about whether or not everybody can hear what you are saying – even the individuals in the most remote corner of the classroom. Luckily, a voice amplifier or a classroom microphone system can easily solve those kinds of worries and issues for teachers. This practical device is a must-have for any type of public speaking, including teaching.

Benefits of Using a Voice Amplifier in a Classroom

Any person who has to address a large number of people, may it be teachers, a tour guide, or a presenter, would benefit greatly from a personal voice amplifier.

• The device can increase the quality of teaching or any kind of speech without causing any discomfort to the speaker.
• As teachers tend to speak for several hours a day and as most of the time they must speak loudly (especially in a classroom full of spirited, sometimes even problematic young people), their vocal cords get strained and (sometimes permanently) damaged. Some teachers lose their voice completely and are unable to speak more than a whisper in old age. A voice amplifier hinders putting unnecessary pressure on the larynx and vocal cords and thus prevents long-term larynx damage. It allows you to speak naturally and makes sure that your words will be heard anyway.
• When students can’t hear their teacher they tend to constantly interrupt him/her, causing time wastage. Using a voice amplifier would prevent interruption and losing precious minutes of your time.
• Using a voice amplifier would keep your voice cords intact and thus enable you to make multiple deliveries of your lesson without getting tired.
• Raising your voice is not only bad for your larynx, it also tends to send the wrong message. With a voice amplifier, you will be heard without sounding aggressive or annoyed and thus causing unwanted misunderstandings.
• Using a voice amplifier tends to make the audience more attentive and at ease.
• Speaking softly without a voice amplifier tends to compromise the speaker’s personal space, as the crowd might gather around him or her to hear the valuable information.
• People with a soft voice may lack confidence when speaking to a large group of people. Using a voice amplifier could boost confidence and make you feel more at ease.
• Using a voice amplifier improves overall audibility and enables even people with hearing problems to follow and understand the lecture.

Tips on How to Use a Voice Amplifier

The first thing you have to keep in mind when using a voice amplifier is to not talk loudly. Make sure to speak in a normal, maybe even quieter tone, otherwise, the sound will come out too loud, which would make it hard to follow or even understand your speech.

Also, do your best to talk slowly. Talking slowly will enable the people at a distance to understand and follow better.

In addition, make sure to always adjust the volume according to your needs and the needs of your audience.

How to Choose a Portable Voice Amplifier

There are many types and brands of voice amplifiers available. To choose the best voice amplifier for you, make sure to take into account a few factors.

1. Ease of use

Make sure the device is user-friendly. For example, check if the microphone is wired or wireless if it can play a background tune if it is waterproof (if you planning to teach outside), and check the input options.

2. Sound Quality

Most voice amplifiers have great sound quality when it comes to speaking. However, if you are planning to sing or play music on it, you may want to choose the device with the best sound quality.

3. Coverage

Check how strong the device is and how far it can carry the sound of your voice. If you are planning on using the device in a mid-sized classroom, a voice amplifier for teachers that can cover a 5,000 square feet area is enough. On the other hand, for an outdoor setting, it might be better to purchase one with 10,000 square feet coverage.

4. Audio storage capacity

If you want to record and store your speech, make sure to buy a voice amplifier for teachers with audio recording ability and either internal memory or an external storage option. Make sure to check the storage capacity.

5. Wired or Wireless

Some wireless voice amplifiers are compatible with Bluetooth and thus enable you to deliver your speech hands-free and to connect it with any Bluetooth-enabled device to play audio.

6. Battery Life/Rechargeable Batteries

If you are planning on using the device outdoors, make sure it has a rather long battery life – around 15 hours. For short lessons and speeches, three-hour battery life should suffice, as you can charge them in between lessons. The average battery life is 3 hours, however, we recommend you to choose a device that can last for at least 4 hours.

Also, consider purchasing a voice amplifier for a teachers with rechargeable batteries, as purchasing tons of non-rechargeable batteries is neither environment-friendly nor cost-effective.

7. Longevity

Check the estimated longevity of your device and buy a sturdy high-quality amplifier.

8. Multipurpose And Portable
