86099-2 is a standard set forth by the International Electrotechnical Commission, otherwise known as IEC. The standard outlines requirements and test methods for the field of electro-acoustical transducers, specifically sound level meters, and it pertains to units of sound pressure level. Below, we will discuss the application field of 86099-2 and its working principle.

Application Field

The application field of 86099-2 centers primarily around sound-level measuring meters and sound-level calibrators. As stated earlier, these devices measure and calibrate units of sound pressure level, or SPL. As such, they are used in any setting that requires accurate readings of sound pressure levels. These settings might include factory floors, medical facilities, busy city streets, and any environment in which sound levels must be regulated or monitored.

In most applications, 86099-2 sound level measuring meters will take the form of a handheld meter or integrated system. They typically have a built-in microphone, speaker, amplifier, and digital reader. This allows for precise, real-time readings of the decibel levels in a particular environment. These meters are usually adjustable, so that users can select the upper and lower limits for acceptable decibel levels.

Working Principle

The working principle of 86099-2 sound-level meters is relatively simple. Basically, the microphone senses sound waves, and the speaker amplifies and broadcasts them. Once the sound waves have passed through the microphone, they are measured by the digital reader and displayed on the screen. The range of decibel levels that can be read is calibrated according to the 86099-2 standard.

The digital reader takes sound pressure measurements in atmospheres, which are then converted to decibel levels according to the 86099-2 requirements. In most cases, these sound levels are displayed graphically, allowing for easy visual interpretation. Additionally, 86099-2 sound level meters are often equipped with advanced sound analysis features, such as frequency, distortion, and reverberation measurement.

Conclusion

To sum up, 86099-2 is a standard specified by the International Electrotechnical Commission. It specifies requirements and test methods for the measurement of sound-pressure levels, and it applies primarily to sound-level meters and calibrators. These instruments use a microphone, speaker, amplifier, and digital reader to measure the decibels in a given environment, which are then displayed graphically. The 86099-2 standard ensures that the measurements taken by these devices are highly accurate and reliable.
