| | Abstract | In the high school setting, musical directors are often in front of groups of |
| | ranging ability, for multiple hours a day. It is a major concern that directors |
| | may experience hearing loss induced by the loud volume levels of the |
| | musical groups. This project focuses on the affects of the musical groups |
| | on the director. It was hypothesized that the sound produced by the |
| | musical groups would be sufficient enough to cause damage to the |
| | director’s hearing. Volume in decibels was recorded from the various |
| | groups, and ability levels that might be encountered in a high school |
| | musical setting. The data contradicted the hypothesis; the decibel levels |
| | produced by the groups were not over the dangerous levels, for a |
| | significant level of time to cause any permanent, significant damage |
