1。 Sound level meter is a kind of according to the rights to a certain frequency meter and time meter measuring instrument for sound pressure level. Can make all kinds of noise according to the determination of the human ear hearing characteristics near the basic equipment, sound level meter outer join or built-in times ( And a third times) Frequency range filter for noise spectrum analysis. 2. Sound level meter is it according to the precision and function is divided into series and a variety of different models. All kinds of noise measuring national related standards ( Precision, measurements and measurement method of sound level meter, noise limit, etc. ) 。 Choice of noise measurement equipment must meet the standard requirements. 3. The choice of sound level meter mainly consider its functions, such as A simple measured noise sound level, simply select the regular sound level meter. For measuring environmental noise, due to the environmental noise fluctuation is bigger, often need to measure the time average sound level or equivalent sound level. For spectrum analysis is required, then to choose the noise spectrum analyzer. 4. Also, according to the measurement accuracy requirements to the level of sound level meter. 5. Sound level meter according to the factors to consider when the choose and buy one by one sorting, such as price, function, accuracy, measurement range, output interface, storage capacity and the number of channels. 6. Sound level meter in use process need to use the acoustic calibrator for calibration, acoustic calibrator is often as a sound level meter of form a complete set of equipment, become a part of the sound level meter. 1.
