![]() The decibel of SPL is a measurement of sound pressure levels in the air. The far away you get from the source of the sound, the pressure will be less, but the loudness will be the same. The difference between SPL and Loudness is that humans do not hear all frequencies at the same level and the closer to the source of the sound, you will hear more pressure. Loudness is the measure of how much sound we can hear. SPL or Sound Pressure Level is a measure of loudness. What is the difference between SPL and loudness? Many manufacturers offer a wide range easy to use and compliant sound level meters for sale to suit your requirement. The SLM is generally produced as handheld, portable devices. It makes a more relevant scale for loudness in health and safety. The Decibel scale is a logarithmic scale that is closer to how the human ear responds to loudness so it is suitable for doing this job. The sound level meter has the ability to measure the sound parameter inĭecibels (dB) which is the standardized method of measuring loudness. Noise meter makes it possible to determine whether the sound is within legal limits. The microcontroller measures, compares, and takes the proper action (makes an audio announcement) to minimize noise level when reaching a critical sound level. Sound pressure level meter (SPL), decibel meter (dB meter), noise level meter ( noise meter), or noise dosimeter.Īudio-frequency sensing ability that is basically controlled by a microcontroller. Sound meter is an electronic instrument toĪssess noise or sound levels produced by workplace machinery, alarm systems, speakers, and more by measuring sound intensity. Let's get a closer look!īrowse our wide selection of Sound Level Meter products category with the highest quality.ĭecibel meters What is a Sound Level Meter? Precise measurements of noise were quite a tricky business in the past, but today automated, electronic sound-level meters are available to do this job. The first thing to help eliminate this problem is to measure how loud it is so the effective steps to be taken to reduce it. Being exposed to loud noises for hours and days can affect the health of the workers and employees in the working environment and also other people and hearing damage may occur. Noise is the most common harmful factor in the workplace. It may have happened to you that you were in a noisy factory and had to cover your ears or walked past a jackhammer in the street and winced because of the loud sound.
