Number meter

A sound level meter is an instrument that is used to measure sound power levels. It is used in a variety of applications, including hygiene practices, where it is necessary to control the noise levels generated by equipment or the environment.

Sound level meters can be used to measure noise levels in various environments, such as industrial premises, residential buildings, offices, etc. They allow you to determine the noise level that can affect human health.

There are several types of sound level meters that vary in their accuracy and functionality. Some can measure noise levels ranging from 30 to 140 dB, while others can measure up to 150 dB.

It is important to note that sound level meters must be properly installed and calibrated to obtain accurate results. In addition, it is necessary to take into account factors that may affect the noise level, such as distance from the sound source, presence of obstacles, etc.

Overall, sound level meters are an important tool for monitoring noise levels in the environment and ensuring public health safety. They help prevent the negative effects of noise on the body and preserve the health of workers at work.

Sound level meters are high-tech devices designed to measure sound levels in a specific space. Moreover, their main task is not only to measure the noise level, but also to determine its nature. Therefore, all professional sound level meters are equipped with the acoustic characteristics of the room, as well as the design features of the umbrella that is installed on the device. The error in determining the value is from 1 to 3 dB.

Several types of devices are now actively used:

1) Phonometers. This type is used when testing the human auditory system and working with individual programs for people suffering from hearing impairment. The phonometer allows you to determine the level and quality of the sounds of the human voice, the sound of heartbeats and other sounds. Due to the microphones installed in the devices with a mini-speaker, this type of device can be considered absolutely safe. 2) Interference noise meter. This device is both a sound and light acoustic tester. While working on its adjustment, the glass vibrates inside, therefore, the sound vibrations of a powerful subwoofer located under the glass frighten a person when performing work under pressure. The sensor is a sound mirror. 3) Spectrum analyzer. This device is contactless and belongs to digital analog-digital devices. They can be used to display the spectra of sound vibrations created by outsiders during operation. Based on predefined indicators, such an analyzer allows you to specify noise indicators that do not exceed those that were specified, and
