Abstract

The equivalent noise levels (LAeq) were measured inside and outside Mina camping during the Hajj season in 1428H (2007) in Makkah (412 m altitude, 21˚.25 N, 39˚.52 E). Measurements were made using the Sound level Meter of model CR812B made by Cirrus Research Company, United Kingdom. These measurements were performed at four camps distributed at different sites in Mina area (Beginning of Mina - Middle of Mina – Streets area – Al-Jamarat area). Results showed that the measured equivalent noise levels per 8 hour at these four camps were ranging between 64 – 78 dB day and night, which is exceeding the recommended noise levels by WHO. Noise levels were similar at all camps during the three days of Al-Tashreeq and the maximum of 74 dB was recorded at camps that were sited in the middle of Mina, while the minimum was at those located at the end of Mina near to Mozdalefah. Moreover, a survey was conducted to evaluate the effects of six health and behaviours factors that the noise might cause. Survey results showed that sleeping disturbance (61%) and difficulty in worship performing (58%) were the most problems that pilgrims were suffering, while the smallest one was vibrations in ear (15%). Some suggestions for diminishing such noise levels in Mina valley during hajj season were highlighted.
