Woofer High
is it true that low frequency voice of woofer creates health problem?
today i was listing the gossip of two doctors , they were talking about a patient who got high blood pressure as wel as heart problem bcz he was addicted of listing very low frequency of woofer for long time in his room .
these winters i am going to purchase a home theater system for my kids , so can u plz tell me that what type of problem can we get with our woofer and are they really serious problem and how can we avoid them plz help
Listening at very high volumes might be dangerous, but loud and very low frequencies are common in many other places and don't cause health problems. Construction sites, large waterfalls/river rapids, driving a truck, etc are all examples.
High frequency sounds will make you go deaf much quicker though.
For your kids hearing sake encourage them not to turn up the volume too much. Some AV Receivers have the ability to set a maximum volume also. I set my Denon recieiver so that it will only go up to -20dB and set it at -50dB when I start it up. To be safer to hearing I could set it to not go any louder than -30dB or so with my speakers.
Listening to loud music or movies for an extended period of time can damage hearing. See the this link for more information http://www.dangerousdecibels.org/hearingloss.cfm
