A sound level meter (SLM) is an instrument (usually hand-held) used to measure sound levels in a standardized manner. It responds to sound in much the same way as the human ear and can objectively measure sound pressure levels. A sound level meter is an instrument used to measure the intensity of sound, and it is important in many different fields and applications. The machine manufacturing industry has taken noise as one of the important quality indicators of the product, auditoriums and gymnasiums, and other buildings do not only require the shape of the beautiful but also the pursuit of acoustics, all of which makes the sound level meter more and more widely used. Buildings such as auditoriums and gymnasiums not only require beautiful shapes but also pursue acoustic effects, which make the application of sound level meters more and more widely.
For you to better choose a suitable sound level meter, sisco store has listed a detailed price list for you.

Sound Level Meter Working Principle
The sound level meter uses a microphone to convert the sound into an electrical signal, and then a preamplifier converts the impedance to match the microphone with the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting on the signal (or an external filter), and then amplifies the signal to a certain amplitude through the attenuator and amplifier, and sends it to the effective value detector (or external press Level recorder), give the value of the noise level on the indicator head.
How Big is the Decibel Scale?
Sound is measured in decibels (dB). Whispering is about 30 decibels, normal conversation is about 60 decibels, and motorcycle engines run at about 95 decibels. Noise above 70 decibels for long periods may begin to damage your hearing. Loud noises above 120 dB can cause immediate damage to your ears.
Overall, sound level meters play an important role in several areas such as human health, environmental protection, industrial safety, recreational experience, and scientific research, helping us understand better, control, and manage the sound environment. sisco.com provides high quality and high precision different types of sound level meters to choose from, if you are interested, welcome to click, we provide professional service and consulting visits.
