Noisiest Shop

The noisiest shops in Bangkok shopping centres are those selling CDs! And the noisiest shops selling CDs are the various branches of Mangpong! Does the volume of their sales really depend on the volume of noise they generate?
One morning I asked a shop attendant next door to a Mangpong branch whether she did not find the noise insufferable. She replied that it was even worse in the afternoons!
Yesterday I told one of the staff in Mangpong that the sound was too high, he agreed, and told me that when he returned home in the evenings his ears continued to ring with the noise. In fact this is a serious abuse of young workers who are therebye more vulnerable. The noise level often exceeds 85 decibels where hearing damage can occur, and the young workers probably work in such an environment for up to 10 hours a day. The 90 db level set as a safety level in the work place in Thai law is not adequate to give protection against the continuous level of noise to which staff in video shops are exposed.
