Sound pollution is one of the most important issues in large and populated cities and reducing it in indoor spaces, including homes, hospitals, etc. has become one of the most important issues in the architecture industry. The unit of measurement is the dB. The intensity of the sound differs in different environments. The approximate range of sources of noise is shown in the following table.

values in dB |
The Sound Of A Shotgun From A Pistol | 150-160 |
Most Voices On The Street | 80-90 |
Maximum Music Sound | 80 |
Vacuum Cleaner | 60 |
Talking | 50 |
General Voices at Home | 40 |
Public Voices In a Park | 30 |
The Sound of Inhaling and Exhaling | 10 |
Silence – The Threshold of Hearing | 0-10 |
In large cities, the intensity of noise is about 65 to 75 dB, while for centers like hospitals that need calmness, it is about 38 dB. The degree of glass insulation versus Sound Transmission is called Class (STC) and is expressed in terms of dB. The higher the amount of this quantity for glass, the higher is the insulating capacity for noise pollution.
