Petition for a 65dB limit for in-class sound media at California Polytechnical University Pomona
As our world around gets louder and louder as the years go by, more and more people are finding out that they have some amount of hearing loss or tinnitus, a permanent and sometimes extremely distressing ringing in the ears for which there is no cure. Whether it is because of a lack of knowledge about how long our ears can tolerate certain dB or sound levels before hearing loss starts, it has been noted that during video or sound presentations in class are above the 85 dB sound limit which is damaging to the fine hairs in the cochlea in the ear after just 15 minutes. This can cause NIHL (noise induced hearing loss) which may also lead to tinnitus. There needs to be a limit set on how loud the sound can be turned up for any amount of time in class in order to protect our students ears for now and the future.
