Importantly, listening at a comfortable level should be safe for an unlimited amount of time, though it is essential to balance duration of use with loudness of exposure. While this sounds like a long time, headphone use at only slightly higher sound levels can cause damage in less than one hour, and it is easy to imagine listening to music with headphones for an hour or longer. The Occupational Safety and Health Administration (OSHA) mandates that employers offer hearing protection for employees with averaged exposure of 85 dB for greater than eight hours. Simply stated, louder sounds have potential for more damage with less exposure. In addition to volume, the duration of sound exposure is an important factor that contributes to possible ear damage. Ultimately, personal listening devices should be comfortable to the listener. This is important to know, because the maximum volume of personal listening devices is above the threshold at which damage occurs (in both children and adults)! It is important that as a listener, you are aware that most devices can, in fact, be used in a way that is harmful. Sound less than 70 dB is unlikely to cause any significant damage to the ears. For reference, exposure to sound levels above 85 dB (equal to a lawnmower or leaf blower) can cause possible ear damage with exposure of more than two hours, while exposure to sound of 105 to 110 dB can cause damage in five minutes. One of the important things to note when considering headphone use is that personal listening devices are tuned to a maximum volume of around 105 to 110 dB. The CDC has detailed information on various daily experiences and the volume, or decibel (dB) level, associated with them. In short, one thing is clear: sound that is too loud is harmful. Damage may also happen via the connection between the hair cells and nerve cells, which can be interrupted by excess sound, even if the hair cells remain normal. Excess sound can cause permanent damage to these cells, which interrupts the mechanism of sound transmission. There are thousands of cells in the ears, some of which have little hairlike structures called hair cells that are responsible for transmitting sound from the ears back to the brain, where it is further processed. Isn’t sound supposed to provide a tool for communication and awareness of our environment? Yes, sound is an essential mode of communication that also orients us to our environment however, the inner ear is very sensitive to the balance of sound that it perceives. There is such a thing as healthy headphone use you just need to know about safe sound levels and when to take a break from headphones. Despite the convenience of headphones and the increased utility, questions about safety of use have been raised. This is particularly true currently, as our society spends more time with virtual meetings and headphones during the COVID-19 pandemic.
The ease of headphone use and the mobility that they afford cannot be overstated. Headphones allow people to enjoy music and have conversations from anywhere at any time. You now have a set of Giant Listening Ears.As our society and culture become more connected through technology, the use of headphones has increased. Last but not least, trim the foam board or cardboard. Trim the labels and apply the labels to the thin foam board or cardboard.
