An integrating-averaging Cirrus Analysis's Optimus sound level meter which complies with IEC 61672-one:2002 A sound level meter (also referred to as sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument by using a microphone. The ideal type of microphone for sound level meters would be the condenser microphone, which combines precision with stability and reliability.[1] The diaphragm with the microphone responds to changes in air strain attributable to sound waves.
