Depending on the nature of their work, employees may experience temporary or permanent illness or disability or mental illness when they are forced to work at a recurring pace or due to the conditions of the work environment. This condition is called occupational diseases.

Among the physical factors causing occupational diseases, noisy environments are among the most notable. Employees may experience hearing loss, sleep disturbances and stress due to noise. In addition, noise can cause workers to change their blood pressure or cause psychological and hormonal disorders. In addition, employees' performance decreases due to noise, behavioral disorders occur and all of these causes work accidents.

If the noise level exceeds 80 decibels in working environments, ear protectors must be used. In general, the earplugs reduce the sound to 20 decibels. The sleeve headphones offer protection up to 45 decibels.

There are many standards developed by domestic and foreign organizations on noise measurements. Here are a few of them:

• TS EN ISO 9612 Acoustics - Determination of exposure to noise in the working environment - Engineering method
• TS 2607 ISO 1999 Acoustics - Determination of exposure to workplace noise and estimation of hearing loss caused by this noise
• TS 2673 Acoustics - Guidance on measuring acoustic noise in the air and assessing its effects on humans
• TS EN ISO 1683 Acoustics - Preferred reference values ​​for acoustic and vibration levels
• TS 9315 ISO 1996-1 Acoustics - Description, measurement and evaluation of environmental noise - Part 1: Basic quantities and evaluation procedures
• TS EN 61672-1 Electroacoustic - Sound level meters - Part 1: Specifications

In rapidly growing cities, houses and workplaces are showing unplanned and intertwined development, as well as increased traffic density, increased use of electrical, electronic and mechanical devices, and so on.

 

It also performs noise measurements in enterprises within the framework of indoor measurements by authorized laboratories.
