Canada Pharmacy Warns Loud Music Lovers of Hearing Loss

Exposure to loud music at a rock concert often results in temporary hearing loss for teenagers, researchers say. A small study by the House Research Institute revealed that 72 percent of teens reported reduced hearing after attending a three-hour show. This type of hearing loss typically disappears within 48 hours, but if it occurs repeatedly, permanent hearing loss can develop, the study authors noted. If symptoms recur regularly there might be a need to buy Optimmune ear drops for faster relief. 

"Teenagers need to understand a single exposure to loud noise either from a concert or personal listening device can lead to hearing loss," study lead author Dr. M. Jennifer Derebery, physician at the House Clinic, said in an institute news release. "With multiple exposures to noise over 85 decibels, the tiny hair cells may stop functioning and the hearing loss may be permanent." 

For the study, researchers offered 29 teenagers free tickets to a rock concert. All of the seats were about 15 to 18 rows away from the stage. 

Beforehand, the kids were told how they could protect their hearing and were encouraged to use foam ear plugs during the performance. Only three chose to use them, the study authors noted. 

Specifically, 53.6 percent of the teens said they were not hearing as well as they did before the concert, and 25 percent reported tinnitus, which is ringing in the ears. 

Although these cells usually recover, the researchers cautioned that repeated exposure to loud noise could permanently damage hearing. Thus, increases the tendency to take generic Cyclosporin. 

"More research is needed to determine if teenage ears are more sensitive than adult ears. Guidelines for noise exposure among teenagers may need to be updated," the authors added. 

"It also means we definitely need to be doing more to ensure the sound levels at concerts are not so loud as to cause hearing loss and neurological damage in teenagers, as well as adults," said Derebery. "Only three of our 29 teens chose to use ear protection, even when it was given to them and they were encouraged to do so. We have to assume this is typical behavior for most teen listeners, so we have the responsibility to get the sound levels down to safer levels." 

The researchers pointed out that "teenagers should take advantage of sound meter apps available for smartphones, which provide an estimate of surrounding noise level, and use ear protection when appropriate." Canada pharmacy sees this as a smart option if music has been a part of one’s daily routine. 

Hearing sensitivity is indicated by the quietest sound that an animal can detect, called the hearing threshold. In the case of humans and some animals, this threshold can be accurately measured by a behavioral audiogram. A record is made of the quietest sound that consistently prompts a response from the listener. The test is carried out for sounds of different frequencies. There are also electro-physiological tests that can be performed without requiring a behavioral response. 

Normal hearing thresholds within any given species are not the same for all frequencies. If different frequencies of sound are played at the same amplitude, some will be perceived as loud, and others quiet or even completely inaudible. Generally, if the gain or amplitude is increased, a sound is more likely to be perceived. Ordinarily, when animals use sound to communicate, hearing in that type of animal is most sensitive for the frequencies produced by calls, or in the case of humans, speech. All levels of the auditory system contribute to this sensitivity toward certain frequencies, from the outer ear's physical characteristics to the nerves and tracts that convey the nerve impulses of the auditory portion of the brain.
