Amplified music from night clubs can lead to hearing damage
Shifts in hearing thresholds can result in excessive exposure to any kind of sound. It not matters whether the sound is pleasant or not nor the music genre, the degree of noise induced hearing loss (NIHL) depends on the intensity and frequency characteristics of the noise, along with its duration and the intermittency of the exposure. Individual genetic and environmental factors also play important part(Bovo, Ciorba, & Martini, 2007).
Hetu and Fortin (1995) studied the characteristics of highly amplified music in discotheques from psychoacoustic and phenomenological points of view. They found that the amplified music is characterized by strong pulsations (≈ 2 Hz), a narrow dynamic range and sloping spectrum with maximum energy in the 1/3 octave centred at 63 Hz. This spectrum, according to Hetu and Fortin (1995), is matching the free field threshold curve elevated by 80 dB. Temporary threshold shift (TTS) can be easily predicted. TTS can be seen as a slow trend of the start of a permanent hearing damage(Dobrucki, Kin, & Kruk, 2013).
Exposure to loud noise damages the Organ of Corti within the cochlea and subsequently leads to an elevation of thresholds. There are two types of damage. An immediate permanent hearing loss can be the result of a very short exposure to an extremely loud noise more than 140 dB. This sound energy can cause a large vibration and detachment of the basilar membrane, the as middle ear structuremay also be involved which lead to additional conductive losses(Clark & Bohne, 1999). Compared with the second type of damage, this kind of insult may be more likely to affect the supporting structures in the organ of Corti, Reissner’s and tectorial membranes....

Sound is localised to the ear by the pinna, travelling down the auditory canal, vibrating the eardrum. The eardrums vibrations are then passed down through the ossicles, three small bones known as the hammer, anvil and stirrup that then transfer the vibrations to the oval window of the cochlea. The cochlea is filled with fluid that when exposed to these vibrations stimulate the sterocilia. This small hair cells "wiggle" along to certain frequencies transferring the vibrations into electrical impulses that are then sent to the brain. If the ear is exposed to noise levels of too high an intensity the sterocilia are overstimulated and many become permanently damaged . (Sliwinska-Kowalska et. All,
Tinnitus, also known as ringing in the ear is a phantom auditory experience which can happen in the absence of an internal or external sound. It often accompanies hearing loss with severity ranging from mild to severe. Although, it can exist as a comparatively harmless condition it can be extremely debilitating and disruptive as it progresses. Tinnitus research has allured neuroscientists for decades due to the mystery related to it’s neural generators. In the recent years, tinnitus research has made some huge strides and has provided new insights to the neural mechanisms, and possible neural generators in the brain. The four major research areas in this field include identifying the brain substructure of tinnitus origin, the neural mechanism behind its origin, developing a general therapy, and customizing therapy for individual patients.
For any individual who either avidly listens to or performs music, it is understood that many melodies have amazing effects on both our emotions and our perception. To address the effects of music on the brain, it seems most logical to initially map the auditory and neural pathways of sound. In the case of humans, the mechanism responsible for receiving and transmitting sound to the brain are the ears. Briefly stated, the outer ear (or pinna) 'catches' and amplifies sound by funneling it into the ear canal. Interestingly, the outer ear serves only to boost high frequency sound components (1). The resonance provided by the outer ear also serves in amplifying a higher range of frequencies corresponding to the top octave of the piano key board. The air pressure wave travels through the ear canal to ultimately reach and vibrate the timpanic membrane (i.e.-- the eardrum). At this particular juncture, the pressure wave energy of sound is translated into mechanical energy via the middle ear. Here, three small bones, the ossicles, vibrate in succession to produce a unique pattern of movements that embodies the frequencies contained in every sound we are capable of hearing. The middle ear is also an important component in what music we actually keep out of our 'head'. The muscles grasping the ossicles can contract to prevent as much as two thirds of the sound from entering the inner ear. (1, 2)
Most successful musicians know a hidden art carried out by the work of a good sound engineer; it is essential for a magnificent album. For the rest of us novice listeners and fans, we believe what we hear through our speakers or played over the radio are the true skilled professional musicians, soaring at their craft. Most contemporary music, from pop to R&B and acid jazz to the sophisticated realm of orchestral film scores, has been modernized by several inventions encased within the studio. The art of audio engineering has taken on new forms, from the nuts and bolts, "plug it in, and see if it works" era into the digital world, because of these wonderfully tragic solutions to a higher pace of life. A musician's art have been made solely because of it, and others have been destroyed and humiliated by it. The complex new inventions of technology shape the adaptive method of studio recording and production however caused a drastic negative musical degrading of our beloved art.
Hearing serves a very important function in our lives. Much of the time, it is taken for granted. We tend not to appreciate it, until it starts to fail. There are many disorders that can cause a difficulty in hearing and hearing loss. One such disorder is otosclerosis. This disorder deserves a significant amount of research. Not only because we are dependent on our sense of hearing, but because its effects are far reaching. So much so, that it is hard to comprehend how we could ever live without it. It has even been said that Beethoven had otosclerosis. Toward the end of his career, he could not even hear his own music (Goldstein, 1999). Its effects are devastating and are well worth studying.
According to Chapman et al., (2000), the loss of hearing appears to be a chronic issue through...
The current hypothesis is that one of my genes is a mutated gene, that mutated gene is what is causing my hearing loss. If this is the real reason why I have hearing loss, there is also worry for what other problems does this mutated gene cause. With finding a mutated gene, they will most likely be able to predict how much worse my hearing will get. Another possible but not likely cause is a tumor, currently, I have to get an MRI to make sure that there is no growth inside of my head. If there is a growth, that will lead to some serious issues. The last possible cause is that loud noises have damaged my hearing, but it is even more less likely than a tumor. I am almost never exposed to loud music, concerts, or anything of that nature, which would causes hearing loss. Since I've been losing hearing since I was 5, they have practically ruled that one out because it makes no

Some people may need assistance in being able to amplify those sound vibrations, which other people’s auditory system may process normally. People that have difficulty hearing may often be referred to a hearing aid device. The device amplifies the sound vibrations which are hear clearly by people without the device, but may not be heard by people who need the device. Hair cells within the ear are able to sense sound vibrations that are louder than usual, and transform them into electrical signals that are sent to the brain and processed as sound. The larger the damage to the hair cell’s in a person, the greater the hearing loss is. Depending on the magnitude of the hearing loss, will also determine the amount of amplification needed to allow for the hearing to reach a normal range. The downfall to this is that there are limitations as to how much you can amplify a sound through the hearing aid device. Also another factor is that if the inner ear is damaged to a certain point, then even with a hearing aid sound vibrations may not be able processed into electrical signals to be received by the auditory nerve

Music can relieve certain medical problems. Parkinsons can be made better with certain musical rhythms. By listening and moving to regular rhythm patterns, people can overcome the effects of parkinson's (Sacks 1). Tourettes can also be made better or worse by performing or listening to songs, depending on what type. Migraines and headaches can be affected by music; again, better or worse. Relaxing or other certain kinds of songs can help out with heart problems. “A review of 23 studies covering over 1,500 patients found that listening to music ...
Sound, music, and hearing have always been a big part of my life. As a lifelong musician, I value my hearing a lot. After playing music on stage at high volume for more than 15 years, I experienced a nasty tinnitus scare. This led me to begin looking into how to protect my hearing. These steps included reducing each member’s volume as well as the overall stage volume so we were able to hear ourselves with less volume. Eventually, with the adoption of in-ear monitors (IEMs) across the band to manage volume on stage and to isolate our own channels (from the drums, especially), I was able to protect my hearing more, and the tinnitus eventually became manageable. This experience led me to realise the importance of protecting my hearing as well
