People are increasingly exposed to noise both at work and at home, as well as inside and outside. Therefore, legal regulations are made and audited in each country. As such, various standards are published by local and foreign organizations in order not to apply different noise measurement methods in different countries. If noise level measurements are carried out in accordance with these standards, manufacturers can develop products that are accepted in foreign countries.

Today there are international standards for mechanical engineering, the automotive industry, home appliances and medical devices. These standards are based on some parameters such as sound power, volume and sound pressure. Sound power is a measure of sound energy emitted over a given time period from a given source and is measured in watts. Each device has its own sound power, independent of the space. Sound intensity is the measure of acoustic energy passing through a particular area. Sound pressure is a floating pressure that occurs above static pressure due to sound. It is the level of noise that a person perceives at the ear level.

In acoustic tests, the sound power parameter is used to determine the noise level of a machine and equipment and to compare it with similar machines. The sound power level of the machinery and equipment tested is tested by two different measuring methods:

• For sound pressure level measurements: TS EN ISO 3740 Acoustics - Determination of sound power levels of noise sources - Guidelines for the use of basic standards
• For sound level measurements: TS EN ISO 9614 Acoustics - Determination of sound power levels of noise sources using sound intensity

During the specific test studies, the current regulations and the relevant standards published by many domestic and foreign organizations are taken into consideration. In line with the needs of the enterprises, our organization also performs acoustic tests within the framework of specific tests.

Meanwhile, our organization has been accredited by ÖSAS accreditation organization in accordance with TS EN ISO / IEC 17025 General Requirements for the Qualification of Testing and Calibration Laboratories and serves within this framework.
