There are two ranges to consider: loudness in decibels (dB, dBA, or dBC) and frequency in hertz (Hz). However, this type of equipment is expensive, with kits starting at over $1,500. If you’re going to do that, you’d probably be better off getting a real sound level meter!Ī personal noise dosimeter attaches to clothing and is used to check accurate exposure rates for an individual. One of these can be a very cheap alternative (and at least one is free), but the accuracy of the measurements is questionable unless an external microphone is fitted. The main issue here is the quality of the microphone, which usually isn’t great and can result in poor readings.

Virtual SLMs: There are a few virtual sound level meters around - software programs that can be used on a laptop, tablet, or smartphone. Most are handheld, and a few can be mounted on the wall to monitor noise continuously. While there may be a few physical differences, they all do pretty much the same job. These meters go by many other names, too, such as sound pressure level meters, decibel meters, noise level meters, and noise dosimeters. A sock, or windshield, usually covers the end of the microphone to take out extraneous wind noise, though it can be removed if necessary. The information is converted to an electrical signal, interpreted by a microprocessor, and delivered to a display. If everything were completely still, there would be absolute silence.Ī sound level meter (SLM) uses a microphone containing a sensitive diaphragm to measure changes in the air pressure. Sound can be described as a pressure wave caused by the vibration of an object. If you’re going to be using sound-analysis software, it’s important to check device compatibility.
