Noise Measurement

Are there any legal regulations related to noise measurement?

On 28 July 2013, the Ministry of Labor and Social Security issued Regulation 28721 of the EMPLOYEE REGARDING PROTECTION OF RISKS RELATED TO NOISE.

The regulation is applied in the workplaces under the Occupational Health and Safety Law No. 6331 dated 20/6/2012.

Noise Measurements TS 2607 ISO 1999: 2005 Acoustics yerinde The noise exposure at work is determined.

What is the point?

To determine the minimum requirements for the protection of health and safety risks that may occur as a result of noise exposure of the employees, in particular from hearing related risks.

What is Noise?

People who have a negative impact on people and are called unpleasant noise.

They usually occur artificially and are undesirable voices whose quality and quantity are impaired.

What are the general effects of noise?

· Physical effects on human health and comfort and hearing damage

· Physiological effects of body activity

· Psychological effects like discomfort, irritability

· Decreased work efficiency,

· Effects on performance, such as no sound is detected.

What are the Effects of Noise on Occupational Health?

· It makes workers uneasy.

· It causes distraction.

· Undesirable behavior disorders such as irritation and excitement occur.

· It affects verbal communication.

· Disrupts sleep patterns.

· Causes damage in hearing and pathways.

· Causes character changes.

What are the effects of noise on business?

· Increases the wrong production rate.

· Yield decreases.

· Causes work accidents.

· Restlessness environment increases.

· Prejudices about the business increase.

· Depending on the operating conditions, work-off actions increase and cause production disruptions.

· The business remains in a difficult position for the law.

· There is an increase in the number of workers and health expenditures.

· Time loss increases.

What are the related terms?

· DB: It is a logarithmic scale which shows the differences between each other and is used to express the quantities significantly.

· DBA: A sound level criterion commonly referred to as A-weighted sound level and used to assess and control the effects of noise, giving more weight to medium and higher frequencies where the human hearing system is most sensitive to low-noise sounds.

Exposure Action Value

· Daily noise exposure level (8h) dB (A): The time-weighted average of all A-weighted noise exposure levels, including the highest sound pressure and instantaneous impact noise, for an 8-hour working day.

· Weekly noise exposure level (LEX, 8h): A-weighted daily noise exposure is a time-weighted average of one week of 5 working days of 8 hours.

The lowest exposure action value: 80 dB (A)

Maximum exposure action value: 85 dB (A)

Exposure limit value: 87 dB (A)



The employer has an obligation to do so. The employer considers the level of noise that employees are exposed to in the risk assessment performed at the workplace and determines the exposure by taking noise measurements where necessary according to the results of the risk assessment.


1. Type, level and duration of exposure, including exposure to instantaneous impact noise,

2. Exposure limit values ??and exposure action values,

3. The impact of all employees on the health and safety of all employees, including those requiring special policy,

4. The effect of the interactions between noise and noise and the effects of vibration and noise on the health and safety of employees,

5. Warning signals used to reduce the risk of accidents and the interaction of noise with other noise to the employees´ health and safety,

6. Information on noise emission of work equipment provided by manufacturers under relevant legislation,

7. Whether there is an alternative work equipment that reduces noise emission,

8. Whether exposure to noise continues beyond normal working hours under the responsibility of the employer,

9. Up-to-date information obtained under health supervision,

10. Determines whether there are ear protectors that can provide adequate protection.


1. The employer shall ensure that the risks arising from exposure to noise are destroyed or minimized at the source and shall determine which measures shall be taken.

2. Other operating methods with less exposure to noise are ed.

3. Select the appropriate work equipment that emits the lowest possible level of noise.

4. The workplace and the work places are designed and arranged accordingly.

5. Employee information and training to ensure the correct and safe use of work equipment
