![]() ![]() Noise-induced hearing loss (NIHL) and decibels There are many combinations of frequency and decibel loss, all of which can be plotted on an audiogram, a visual representation of a person’s degree of hearing loss.Įven slight hearing loss is associated with cognitive decline, and it’s important to note that all hearing loss should be treated with hearing aids or additional actions, regardless of age. However, hearing loss is complex and distinctive to each person and changes over time. For example, a person with mild hearing loss might not be able to hear rustling leaves and water drip (~10dB) like someone with normal hearing would.Īs we age, it is common to obtain hearing loss in higher frequency sounds. To make it easy, the degree of hearing loss is measured two ways - how loud something needs to be before you can hear it and what frequencies are more difficult for you to hear (such as higher-pitched women’s voices compared to men). How is hearing loss in decibels measured? Sporting events – 105 to 130 dB (Stadium dependent).Audio headset player at maximum volume – 105 dB. ![]() Hearing protection should be used at all times when handling them, so you do not develop shooter’s ear.*Note – Sound ratios are not to scale. This is a significant reason that guns are considered harmful to your hearing. You can see, firearms are substantially louder than city traffic, and an increase of 65 dB is exponentially much louder. So, we put together a chart to better understand how everyday sounds measure on the decibel scale. ![]() Unless you are a hearing professional, being told that a particular sound is at a specific decibel level won’t hold much weight. If a sound is 20 dB, that pushes it 100 times louder than near silent. Near silent is defined as 0 dB but a sound gauged at 10 dB is ten times louder. For example, for every 10dB increase on the dB scale, it equals a ten times increase in sound pressure level (SPL). This is a way of measuring something that is rapidly or exponentially increasing. ![]()
