In 2011 the percentage of the American population affected by Noise Induced Hearing Loss (NIHL) was 15.3%. Unlike most forms of hearing loss, this can be prevented by limiting exposure to certain magnitudes of noises for varying amounts of time. The present study aims to assess the sound which can contribute to NIHL given off from dropping free weights using six calibrated smartphones in the gym at the University of Birmingham. This report sets out to measure the noise and vibration given off by dropping loaded barbells at the top of a deadlift. By conducting these tests, it can be assessed whether the sound given off from dropping free weights in the gym could be contributing to NIHL. A relationship between drop weight and the vibration is also be constructed. For vibration, it is found that vibration level (m/s 2 ) increased with drop weight, whereas the average noise level for each drop weight only varies by a range of 4.4 dB between 102.7 dB and 98.3 dB. There is no correlation shown by these results between sound level and drop weight, however, all the sound levels recorded are over 85 dB leading to NIHL. This study reminds us that measures need to be taken to reduce the sound level from the dropping of loaded barbells in the University of Birmingham Sports and Fitness Centers
