The golden standard for sound noise level meter reimagined with the Dewesoft approach. Easy to set up and use while ensuring maximum accuracy with certified compliance with international standards. No matter the type of acoustics measurement, a sound level meter is always at the heart of the sound analysis.
A sound level meter is used for acoustic sound measurements. Sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level.
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.
Sound level meters require a microphone sensor to measure the sound. The best type of microphone for sound level measurement is the condenser microphone, which combines precision with stability and reliability.
A sound level meter uses four main components - a microphone, a preamplifier, signal processing, and a display. The microphone converts the sound signal to an equivalent electrical signal. The most suitable type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. The electrical signal produced by the microphone is at a very low level and made stronger by the preamplifier before it is processed by the main processor typically software.
Signal processing includes applying frequency and time weightings to the signal as specified by international standards such as IEC 61672 – 1, to which sound level meters conform.
Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average, or equilibrium) atmospheric pressure, caused by a soundwave. In the air, sound pressure can be measured using a microphone, and in the water with a hydrophone. The unit for the sound pressure is the pascals (symbol: Pa).
Sound pressure level (SPL) or sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. The standard reference for the sound pressure in an air or other gases is 20 µPa, which is usually considered the threshold of human hearing (at 1 kHz). Learn more.
