One of the harmful factors that negatively affects well-being and human health is noise. No wonder people working in conditions of strong sound exposure, relies surcharge or additional days of rest. To estimate the noise level, there are special appliances. Through the microphone to the device the sound gets caught, which is then converted to decibels, and the results are displayed on the sound level meter. Today in Russian stores A wide range of these appliances is presented. Among them there is how professional models and home appliances. Recommendations Our experts will help potential buyers find their noise meter.

Filters One of the most important elements in a sound level meter is sound filters. They are 4 species, each of them is responsible for sound level and degree of its pressure. In noise meters most often two filters are applied.
- The sound filter marked A is responsible for the operation of the device and demonstration of the data at a small level volume.
- Filter C is required to determine the degree of maximum volume.
Classification. All noise meters for accuracy are divided into 4 categories.
- The zero class is distinguished by the most accurate measurements, its the scope is very narrow due to the space price.
- For certified laboratories conducting experimental works created first-class appliances. They are distinguished by minimal an error.
- High noise metering devices demonstrate the second class. These are the most common devices in industrial sphere. They allow you to monitor the state of sound exposure, both in the whole room and in a limited area.
- In everyday life, high accuracy of noise measurements is not required. Man it is important to know the approximate value in order to conclude safety one or another technique. In this case, the device must be accessible by the price. The third class models meet all these requirements.
Temporary properties. Noise meters differ and time intervals of measurements.
- Assess noise exposure continuously allow devices marked F (fast).
- If the task is to measure noise with interruptions in work, then models like S (slow) will do.
- To measure pulsed sounds, it will take devices marked I (pik).
Additional options. In sound level meters manufacturers introduce different modern options.
- The backlight of the display allows you to take readings in poor conditions visibility.
- Communication with a personal computer allows you to organize a connector USB
- An analog output is required to connect to the oscilloscope.
- Built-in memory allows you to store specific number of measurements.
We selected 8 best sound level meters in the review. You can purchase them at trading network of our country. When allocating seats, the editorial board based on expert opinion, taking into account reviews of Russian consumers.
