Hearing protection is all too often overlooked.
When our ears are inundated with decibels, we may have a ringing or "fuzzy" feeling afterwards. That is called "temporary threshold shift", and that is your hearing thresholds (the softest volume that you can hear) being changed. Your ability to hear quiet sounds actually gets worse for a period of time. In other words, you experience a temporary hearing loss...or IS it temporary? There have been studies that suggest that on a very small level, a part of your auditory system may actually experience permanent damage.
If you experience enough of these temporary threshold shifts, it will become a permanent threshold shift-in other words, a detectable hearing loss. We tend to naturally lose high frequency hearing just from living. Add to that extreme volume levels, and you are asking a heck of a lot of a very tiny anatomical system.
You cannot shut your ears off. The mechanisms that allow us to process waves in the air into impulses of sound to the brain are on 100% of the time and the fluid in your inner ear is always moving which in turn is constantly causing motion of the hair cells in our inner ears. These hair cells are extremely durable, but they were never intended to process the abuse that our modern life presents. Once they are displaced, there is no recovering the hearing that is controlled by those hair cells.
Many of our patients report noise exposure that came at a time when ear protection was just not a thing that people did. The hazards of high levels of noise are well documented today and the options for hearing protection are vast, yet hearing protection is still not on the radar of many of the people that need it the most.
Without going into much detail about decibel levels and exposure time, let's just say that if you have to shout to be heard, the environment is likely too loud to be safe. Hearing loss usually manifests very slowly and is focused on a small section of our hearing at first. This small notch in our hearing is very easily overlooked since the rest of your hearing may be pretty good. As the assault to your ears continues, you can expect that notch in your hearing to worsen and spread. I have seen MANY patients with fantastic low frequency hearing that plummets in the high frequencies, and this very often makes it hard to detect the hearing loss for that person. They can hear so well in low and maybe middle frequencies that they don't notice the high frequency loss. These high frequencies are where the clarity of speech is, so you can hear people talking but may struggle to understand them or follow conversations. This is especially the case when there's some background noise.
If nothing else, foam ear plugs from any drug store will help. If you require something more, there are many options of filtered earplugs sold as "one size fits all" and beyond that, custom earplugs can be a game changer. There are specialty plugs for shooters, for musicians, for swimming, or even custom plugs just for a quieter environment (sleeping, studying, etc). We offer all of these options and work with a few different manufactures that pretty much just do earplugs or earmolds for hearing aids.
If you only want to keep really loud stuff out, foam plugs and/or earmuff hearing protection is fine. For shooters, it is recommended to use BOTH at the range. If specialty plugs are needed, we take ear impressions to ensure that the ear plugs will fit your specific ears, and then they are made in whatever color combination you'd like. Swimmer's plugs float just in case they do pop out, shooter's plugs have electronic components that allow you to hear and activate only when sounds above a certain decibel level are presented, and musician plugs are specially filtered to allow the sound to be at a reduced volume without compromising the frequency response. You can even get custom tips for your earbuds or communication earpieces.
Whatever method you use, use it consistently. FYI, a small pill carrier on a keychain can be repurposed to carry a set of earplugs everywhere. Protect what hearing you still have so that you don't need to come and see us down the road
For fun, here's a photo of the hair cells in a healthy ear and one that has experienced a great deal of damage:
