Sound measuring device.

What is a Sound Level Meter? A Sound Level Meter (SLM) is an instrument (commonly hand-held) that is designed to measure sound levels in a standardized way. It responds to sound in approximately the same way as the human ear and gives objective, reproducible measurements of sound pressure levels. BUYERS GUIDE. Another important and easily measured factor is sound intensity, or volume. We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Decibels (dB) are named in honor of Alexander Graham Bell, the inventor of both the telephone and the audiometer. An audiometer is a device that measures how well a ... Accuracy refers to the degree to which the measurements of a sound measurement device are close to the true or actual values. An accurate Class 1 sound measurement device will provide readings that closely match the real-world values of the sound it is measuring. This can include the sound’s frequency, amplitude, and other relevant parameters. Auto power off function, Set fast/slow response time, Possible to mount on a tripod. 1 year.
