Choosing the Best Decibel Meter for Noise Measurement

decibel meterIf you are curious or concerned about how loud the noises and other sounds in your environment are, then you might want to buy a decibel meter. It’s a convenient tool to have when you want to precisely determine the loudness of sounds in a room or another environment.

But choosing from among the many decibel meters for sale can be quite confusing for some; that’s why reading up on consumer reviews can be helpful. Later on we’ll show you the top sound level meters according to user ratings and reviews.

What Is a Decibel Meter?

Also known as a noise dosimeter, decibel reader, or noise level meter, a decibel meter is a device that measures the intensity of sounds using the decibel (dB) unit. It lets you know just how soft or how loud noise is. A normal conversation, for example, would measure about 50 decibels. Compare that to the noise at a live rock concert, which typically measures upwards of 100 decibels, and you will probably see just how useful a decibelmeter can be.

Why Use a Noise Decibel Meter?

Health experts say that being exposed for too long to sounds that measure more than 85 decibels can result in hearing damage or impairment. This is why those in the live music industry regularly use sound level meters to set up and adjust instruments’ sound levels at concerts.

An audio meter is also used in certain work environments where loud noises usually occur, in order to protect workers from hearing loss. Someone operating a jackhammer on a construction site, for instance, would need hearing protection since a jackhammer emits a noise of around 100 decibels. A firecracker, on the other hand, produces a noise of about 140 decibels; so imagine the kind of risk of hearing loss that those who work with explosives are exposed to if they don’t take the proper precautions to protect their ears.

What to Consider When Buying a Noise Level Meter

Not all decibel meters offer the same capabilities and features. A lot of them are capable of noise measurement levels of 30 up to 130 decibels. However, there is also a number of noise dosimeter devices that have a wider measurement range that is capable of detecting audio that would seem distorted to the naked ear.

You should also consider the environment wherein you will be using a sound meter. Some decibel meters are designed to work best in enclosed spaces and thus would not give the optimum reading if used outdoors.

Should you go for a handheld audio meter or one that you can plug directly into an audio device? It depends on your needs and budget. Handheld sound level meters have a microphone that detects sound and measures it accurately. Some professionals prefer using the pluggable device, even though it tends to be more expensive, because it directly analyzes the sound of a piece of audio equipment.
