Abuja the capital city of Nigeria has experienced rapid development and high influx of people with the implication of increased generation of noise. Hence the need to evaluate the noise pollution level of the city. Measurement of equivalent noise level was carried out in 35 locations around the city using a CR811C integrated sound level meter. Result showed that the day time mean equivalent noi...

This study aimed to assess exposure to sound and the risk of noise-induced hearing loss (NIHL) in orchestral musicians. Sound pressure level was measured in 1 opera and 3 symphony orchestras; questionnaires were filled in. On the basis of that data, the risk of NIHL was assessed according to Standard No. ISO 1999:1990. Classical orchestral musicians are usually exposed to sound at equivalent co...

We measured the sound level and frequencies of the acoustic noise generated by a 3 Tesla (T) MR scanner, and investigated the subjective sound level for 30 healthy volunteers with either earplugs, headphones or both. The sound level of 3T was found to be higher than that of 1.5T in all sequences. The peak sound pressure level of 3T ranged from 125.7 dB for MR angiography to 130.7 dB for single ...
