5 Ways to Damage Your Hearing

We are all guilty of listening to something at a volume that is too high.  It might be music or machinery or even a kitchen household appliance like a blender. But there are other things that you might be doing that can damage your hearing and you might not have even been aware they were a problem.

The following is a list of ways that you can do permanent damage to your hearing.  This list was compiled in part from the following article by ABC News

Ear Buds

“Our ears really weren’t meant to listen to music at the level we’re listening to it for hours and hours,” said Dr. Geroge Alexiades, an otologist and neuro-otologist at the New York Eye and Ear Infirmary.

But Alexiades pointed out that the problem is not necessarily having music playing so close to the ear but when that music is played loudly to drown out other sounds using earbuds that were not made to plug the ear canal.

“With earbuds that don’t block background sound, people crank up their music louder,” Alexiades said. “The intensity of sound we can listen to depends on how long we can listen to it.”

Using earbuds can also show how hearing can change after long exposure to certain noise levels. Eventually, our ears undergo a temporary threshold shift, when our perception of normal volume changes and it is difficult to hear softer noises — after a rock concert, for example.

The effect, however, is usually temporary and hearing will return to normal within several hours if no lasting damage was done.

While earbuds plug the ear canal and block ambient noise so that music may be played at a lower level, doctors caution that this can be dangerous in situations where noise cues are important for safety — while driving or walking on a street, for example.


According to an October 2009 study, the noise associated with driving a convertible can damage hearing over time.

“The more you [drive], the more chance you have of developing permanent problems,” said Dr. Philip Michael, an ear, nose and throat surgeon at Queen Elizabeth Hospital, in Birmingham, England, who presented his findings at the October meeting of the American Academy of Otolaryngology. “It’s a cumulative risk.”

“There’s a humanitarian reason for [this research] but also another reason, which is that I like cars,” said Michael, who drives an Audi convertible.

But Michael’s findings revealed more than personal taste. Measuring the sound a driver will hear in several types of convertibles, including a Toyota MR2, an Aston Martin V-8 Vantage, and a Porsche 997 Carrera, at speeds between 50-70 miles per hour, Michael found that drivers are exposed to noise levels of 88-90 Decibels (Db).

The average conversation is held at about 50 Db, street traffic is about 70 Db, and an operating lawnmower is about 90 Db. Repeated exposure to over 85 Db is known to cause permanent hearing loss.

Greg Fletcher, 49, of Orange County, California, has owned a vintage Jensen Healey convertible since 1985, and said he is all too aware that convertibles are not the peaceful joy ride of people’s fantasies.

“A convertible is something pleasant to drive on country roads at 40 mph,” Fletcher said. “But [in my car] there’s not much insulation, the engine is noisy, it vibrates a lot… Even with the top up I can’t talk on the phone.”

But the noise of the car is not the primary problem, Michael said. Wind noise at high speeds and traffic noise as lower speeds are worse.

“When you’ve got a truck next to you, it’s deafening,” Fletcher agreed. “It’s the most awful thing, and you just want to get away as quick as you can.”

Although Fletcher is not sure that driving his convertible several days each week will cause deafness, he said many owners know a convertible is not the best way to protect hearing.

“It’s hard to say. I don’t think my hearing is quite as good as it used to be,” Fletcher said. “It hasn’t gotten to a point where it’s interfering with my daily life. But it’s probably contributed in a negative way over the years.”


While the lungs and heart take the brunt of the damage from smoking, the ears can be affected as well.

One blood vessel serves the cochlea, the sense organ of the inner ear, and restricting blood flow can prevent enough oxygen from reaching it.

Nicotine, a vasoconstrictor that causes blood vessels to shrink slightly, can have a profound effect on the small capillaries that serve the ear.

“The ear is tenuous and has a high demand for blood flow,” Rauch said. “Every time you light up a cigarette, you are minimally reducing blood flow to the ear. Over a lifetime of being a smoker, you are suffocating the ear a little bit.”

Although one study, published in the Journal of the Association for Research into Otolaryngology, showed that smokers have more difficulty hearing high frequency sounds compared to non-smokers, and that hearing deteriorates after smoking regularly for more than a year.

Your Job

Toxic noise that leads to mechanical injury in the cochlea is one of the most important factors in hearing loss. But a noisy environment goes hand-in-hand with many occupations.

Musicians, construction workers, factory workers, and firemen are some of the people at high risk for constant exposure to loud noise.

“Research indicates that noise injury is a gift that keeps on giving, like a snowball down a hill,” said Rauch. “Noise between 70-90 Db does slowly cause increased wear and tear on your hearing… That is a huge implication for occupational impact noise exposure.”

Loud noise can cause injury by damaging the hair cells in the cochlea by bending and vibrating in response to sound. Loud sounds force those cells to flex with greater magnitude until eventually they break or wilt and don’t respond to noise properly.

“If you beat on those hair cells hard enough they die,” Rauch said. “Those cells never regenerate.”

Since noise is a dose effect, sudden loud sounds can be just as if not more damaging than prolonged exposure to 80 Db of noise over eight hours in a factory, for example. A gunshot sounding at about 150 Db can do the same amount of damage in a fraction of a second as the accumulated injuries a musician might have, for example, and this can be an issue for war veterans, for example.


Diabetics are at risk for impaired hearing because their blood vessels are abnormal, Rauch said.

“Impairment of blood flow to the ear is bad,” Rauch said. “It can go dead, like a stroke.”

Narrow or abnormal blood vessels can prevent sufficient blood from reaching the cochlea as well as prevent toxins from getting cleaned out. This has the potential to damage the delicate cells within the ear.

“Diabetics can lose their hearing bit by bit,” Rauch said. “It’s not sudden deafness.”
