The energy in a sound wave can be measured using Decibels. The Decibel Meter shows examples of things that make noise and measurements in decibels. Amplitude measures how forceful the wave is. It is measured in decibels or dBA of sound pressure. 0 dBA is the softest level that a person can hear.
Sound Level Meter Navigation. The sound level meter is an instrument that determines the sound level by measuring the sound level pressure. Sound enters the sound level meter by means of a microphone input. The sound is then evaluated within the device and measurement values in decibels are displayed. A PCE sound level meter is manufactured in line with the highest industrial standards.
