Sound level meters are great tools to use to monitor and manage sound levels in the classroom. They can help teachers maintain an environment conducive to learning by providing real-time sound level readings and allowing them to adjust sound levels accordingly.

I have already covered some of the best web-based sound meter tools to use in class. In this post, I will discuss some of the best sound level meters available on Amazon specifically designed for classroom use. I did an extensive online search, dug into the piles of user reviews and came up with the list below. I hope you find it helpful.

What is a sound level meter?

A  sound level meter is a device used to measure sound or noise levels. It measures and records sound pressure levels in decibels (dB). The purpose of sound level meters is to help people understand and control sound levels in their environment.

What are the benefits of sound level meters for classrooms?

Sound level meters can be used in classrooms to monitor sound levels so that sound doesn’t become too loud. This can help teachers and students remain focused because high sound levels can be too distracting.

Needless to mention that high sound waves can sometimes have detrimental impact on our hearing abilities because they can damage hair cells, and as one study confirms, damaging hair cells which act as sound receivers in our ears, can sometimes lead to what is known as noise-induced hearing loss. 

Another useful way teachers can employ sound level meters in class is through using them as educational tools to educate students on the concepts of sound levels and how sounds function in our everyday life.

What criteria to consider when shopping for a noise level meter?

When shopping for sound level meters, it is important to consider the features that each device offers. Some sound level meters may come with special features such as Bluetooth connectivity, sound visualization tools, adjustable frequency levels, or sound analysis.

It is also important to consider the accuracy of the device and its range of coverage in order to make sure that sound measurements are accurate. Additionally, sound level meters that are portable can be more convenient for teachers and students who need to move them around in the classroom.
