Study of Environmental Noise Pollution in the University,
Inside the UD campus, levels of noise were the highest at locations that are characterized by the high traf fi c movement. In addition, the highest level of noise was recorded during the studying period, while the lowest level was obtained during the holiday period. Levels of the indoor noise inside buildings of the campus were nearly the same or very slightlyAnalysis and Evaluation of Road Traffic Noise in Al-Dammam,,The commercial-zone day average sound level L d of 80.2 dB (A) exceeded the maximum permissible limit used in Kindom of Saudi Arabia ( Table 1) by 15.2 dB (A); the value for the residential zone exceeded it by 23.4 dB (A) while that of the mixed residential-and-commercial zone was above limit by 21.1 dB (A).NEA | Industrial Noise Control,Maximum permitted noise levels (reckoned as the equivalent noise level over the specified period) in decibels (dBA) Day (7am-7pm) Evening (7pm-11pm) Night (11pm-7am) Noise Sensitive Premises: 60: 55: 50: Residential Premises: 65: 60: 55: Commercial Premises: 70: 65: 60Sound level meter – standard-compliant measurement,,The so-called guideline sound level values and emission values govern this, setting out a range of approximately 55 to 85 decibels as not presenting any health risks. The guideline values differ depending on the workplace: if the sound level meter indicates 70 decibels in a mechanical production facility, that is in the minimum range.Saudi Arabia imposes restrictions on use of loudspeakers,,30/05/2021· Nearly two years after discussions surrounding the limit to the usage of loudspeakers in and around mosques began, the Kingdom of Saudi Arabia has issued a notification banning the use of outer loudspeakers in mosques across the Middle-Eastern country. The Arab state has imposed restrictions on the use of loudspeakers in mosques based on thecalibration service Companies in Saudi Arabia,Cirrus Research plc is a world-leading manufacturer and supplier of sound level meters, noise meters, noise dosimeters, environmental noise monitoring systems and acoustic transducers.

UAE authorities have rules to curb excessive noise
Dubai Municipality said that noise from any type of construction or demolition site should not exceed 55 decibels between 7am and 8pm and 45 decibels between 8pm and 7am.
