One of the harmful factors that adversely affects human health and well-being is noise. It is not without reason that people who work in conditions of strong sound exposure are entitled to extra pay or extra days off. To estimate the noise level, there are special instruments. Sound is fed into the device through a microphone, converted into decibels, and the results are displayed on the noise meter. Today there is a wide range of these devices in Russian stores. There are professional models as well as household devices. Recommendations of our experts will help potential buyers to find their noise meter.
Suggestions for selection
Filters. One of the most important elements in a noise meter is the sound filter. They come in 4 types, each of which is responsible for sound level and pressure level. Two filters are most often used in noise meters.
- A sound filter designation is responsible for device operation and displaying data obtained at a low volume level.
- C-filter required for maximum volume.
Classification. All noise meters are divided into 4 categories according to their accuracy.
- Zero class has the most precise measurements, but its field of application is very narrow due to the space price.
- For certified laboratories, experimental work devices of the first class are created. They are distinguished by their minimal error.
- Second class devices have a high level of noise measurement. These are the most common devices in the industry. They allow you to monitor the condition of the sound impact, both in the entire room, as well as in a limited area.
- High accuracy of noise measurements is not required in the household. It is important for a person to know the approximate value in order to draw a conclusion about the safety of a particular piece of equipment. At the same time the device should be affordable. All these requirements are met by models of the third class.
Temporal properties.Noise meters also differ in time intervals of measurements.
- Instruments labeled F (fast) allow you to estimate the degree of noise exposure in continuous mode.
- If the task is to measure noise with interruptions in operation, then the S (slow) models are suitable.
- To perform impulse sound measurements, you will need devices marked I (pik).
Additional Options.Noise meter manufacturers introduce various modern options.
- Illuminated display allows to take readings in poor visibility conditions.
- The USB port allows communication with a personal computer.
- Requires analog output for connection to an oscilloscope.
- Built-in memory allows a specified number of measurements to be stored in the device.
We have selected the 8 best noise meters in this review. You can buy them in the trading network of our country. When assigning the places, the editorial staff of expertology magazine based on expert opinion, taking into account feedback from Russian consumers.
