Listening to the frequency of very high volumes, could be dangerous, but powerful and very low are common in many other places and do not cause health problems. Construction sites, large waterfalls / rapids of the river, driving a truck, etc., are examples. The sounds of high frequency will make you go much faster if deaf. For the love of young people to encourage your audience does not mount the volume too. Some AV Receivers have the opportunity to set a maximum volume as well. I put my Recieiver Denon so that it will only go up to 20dB and set it to 50dB when I started. To be more sure of hearing, I could set it to not go higher than -30 dB or my speakers. listening to music or movies for a period prolonged time can damage hearing.
