Overcoming Hearing Loss Of The Left Ear?
, I want to ask. It’s been 3 months I feel the strangeness of my hearing. First, I feel the left and right ears are different in capturing sound, I feel the right ear is more sensitive in hearing. Then when listening to music using earphones some frequencies cannot be captured by my left ear, and I feel like there is a distortion (crackle-crackle) in my left ear when listening at frequencies of 15000hz and above. I know because I test using the YouTube video hearing test. My right ear is still able to listen up to 18000hz +, I am 23 years old. I was very disturbed, because I also worked in the music field. Where hearing is very important to get sound details.
Hello Rizal, thank you for the question.
As you know, the human ear can pick up sounds from 20-20,000 Hz. The human ear can pick up the most sensitive sounds at about 3000-5000 Hz. This means that at that frequency, humans can easily recognize and distinguish frequencies. The range of sounds that can be produced by humans is around 300-3000 Hz (numbers can differ depending on the reference reference). Thus, in general, the sound of conversation that we hear everyday, ranges around 1000 Hz.
Hearing loss can be in the form of deaf conduct and nerve deafness. Deaf conduct is caused by disorders of the hearing organ, for example due to ear infections, eardrum tears, or ear canal obstruction. Nerve deafness is caused by damage to recipient cells that stimulate sound. Nerve deafness is most often caused by prolonged exposure to loud volume sounds. For example due to loud noise from:
etc. The maximum volume that can be heard by humans without time limit is 70 dB. At 80 dB or 85 dB sound, the listening time limit is 8 hours per day. For each increase of 3 or 5 dB of this number, the length of time listening must be reduced by half. So, if 80 dB can only be heard for 8 hours maximum, then 83 dB can only be heard for 4 hours maximum. And so on every multiple of 3 or 5 dB.
Sounds with a volume above 90 dB cause damage to recipient cells that stimulate sound. Sounds of 120 dB and above cause permanent damage. The problem is, often humans do not immediately realize the existence of deafness, because deafness generally occurs at high frequency first. So, because humans generally listen more to conversation, the ability to hear conversation may not have been disturbed, so deafness is not realized. Today more and more people of productive age are starting to experience nerve deafness due to the habit of listening to loud volume devices. You should check with your doctor. The doctor will conduct a hearing test, in the form of a tuning or audiometry test. If the result is nerve deafness, then deafness can be temporary or permanent. The doctor will explain this and make a plan of action.
Limit the volume of sound you hear everyday. Use personal protective equipment such as earplugs and earmuffs.
Hopefully this explanation can be useful. Regards.
