Recommended: Noise pollution and irritability

Harmful noises are everywhere. “The National Institute of Occupational Safety and Health (NIOSH) reports that approximately 30 million Americans are exposed to daily noise levels that will likely lead to hearing loss” (Daniel, 2007, p. 226). Excessive noise exposure can lead to permanent hearing loss, tinnitus, poor communication abilities, and reduced self-esteem; however, it can be prevented in many situations. This paper will discuss how much noise exposure can occur before it becomes hazardous, the long-term effects of noise exposure at an early age, and the primary reasons why preventable socioacousis occurs.

The amount of damage resulting from noise exposure depends on the intensity level of the noise in relation to the length of time exposed to the noise. According to NIOSH, sound levels that exceed a time weighted average of 85 decibels dB(A) over an 8-hour period of time are considered dangerous. It is recommended that exposure time be decreased by half for every 3 dB increase in intensity that exceeds 85 dB because noise exposure increases with time and intensity (NIOSH, 1998). Impulse sounds such as gun fires or firecrackers can exceed 150 dB(A) and cause immediate, irreversible, sensorineural hearing loss (Axelsson & Jerson, 1985). Most people are unaware of the decibel system and how much 85 dB equates to, but according to the article, “How loud is too loud? Minimize noise exposure to protect your hearing”, if someone has to yell to be heard, it is probably loud enough to cause hearing damage, (Johnson, 2011).

To further evaluate the effects of noise exposure Kujawa and Liberman conducted a study to determine the long-term effects of noise exposure in relation age. They presenting the same amount of 8–16 kHz oc...

  • Understanding Noise-Induced Hearing Loss

    903 Words  | 2 Pages

    The unit used to measure the intensity of sound is called the decibel(dB). Sounds that measure up to 75dB are considered to be in the "safe zone". Constant exposure to to sound at these levels are very unlikely to cause any lasting damage to long term hearing. The sound of regular volume conversation measures at around 60dB and the sound of a running dishwasher measures at roughly 75dB. Sounds around the 85dB level are considered a moderate risk to hearing. Exposure at these levels for extened periods of time may lead to some form of damage causing NIHL. Sounds at these levels include heavy traffic and crowded areas at 85dB, active subway stations at 95dB and listening to an mp3 player with ear buds at maximum volume at 105dB in which listening for just 15 minutes can cause permanent damage. Sound at 120dB and above are in the "danger zone". This level of sound is to be avoided at all cost as exposure even for a short pulse will lead to immediate permanent damage. This level includes the sound of ambulance sirens at 120dB, a jet taking off at 140dB and gunshots at 165 dB and above. (Rabinowitz,

  • Cochlear Implants Essay

    1836 Words  | 4 Pages

    There is no denying that hearing loss can have significant psychosocial impacts on those who experience it. The most negatively impacted group, however, is young children, for whom hearing loss can impede early learning and development (Connor et al., 2006). One viable solution to this problem takes the form of cochlear implants. An artificial cochlear unit is surgically implanted in the ear and functions by translating sounds directly into electrical impulses and sending them to the brain (Roland & Tobey, 2013, p. 1175). Despite the high success rates that they have produced, critics contend that cochlear implants should not be carried out on very young children. They cite certain physiological concerns as well as doubts about long-term effectiveness (Hehar et al., 2002, p. 11). Some have even expressed worries that cochlear implants will negatively impact young children’s social development by making them feel different or out of place (Ketelaar, 2012, pp. 518-519). Certainly, not every child with hearing loss is a viable candidate for an implant procedure. However, when a candidate has been positively identified, the procedure should take place as early as possible, in order to guarantee maximum educational and developmental benefits.

  • Hearing Loss Essay

    1631 Words  | 4 Pages

    Hearing loss is a major global public health issue. Hearnet (2017) defines hearing loss as “a disability that occurs when one or more parts of the ear and/or the parts of the brain that make up the hearing pathway do not function normally” (para. 1). There are many different types of hearing loss, which can have multiple causes, giving each individual experiencing the issue a unique hearing loss case. These types include Auditory Processing Disorders, when the brain has problems processing sound information; Conductive Hearing Loss, a problem with the outer or middle ear which prevents sound making its way to the inner ear; and Sensorineural Hearing Loss, when the Cochlea or auditory nerve is damaged and cannot

    1. Hearing Problems: Any unwanted sound that our ears have not been built to filter can cause problems within the body. Our ears can take in a certain range of sounds without getting damaged. Man made noises such as jackhammers, horns, machinery, airplanes and even vehicles can be too loud for our hearing range. It also reduces our sensitivity to sounds that our ears pick up unconsciously to regulate our body’s rhythm.

  • Aging and Hearing Loss

    There are many approaches to the explanation of the elderly's difficulty with rapid speech. Researchers point to a decline in processing speed, a decline in processing brief acoustic cues (Gordon-Salant & Fitzgibbons, 2001), an age-related decline of temporal processing in general (Gordon-Salant & Fitzgibbons, 1999; Vaughan & Letowski, 1997), the fact that both visual and auditory perception change with age (Helfer, 1998), an interference of mechanical function of the ear, possible sensorineural hearing loss due to damage to receptors over time (Scheuerle, 2000), or a decline in the processing of sounds in midbrain (Ochert, 2000). Each one of these could be a possible explanation; however it is often a combination of several of these causing a perceptual difficulty in the individual.

  • The Many Benefits of Active Noise Cancellation

    One of the major problems that society faces today is noise pollution. Everywhere people go there is always something that is making a sound. It can be very loud such as a plane flying overhead, or it could be quiet like the fan of a computer. When a person is exposed to certain noises for extended periods of time it can not only damage their hearing, but also effect their mood, energy level, and productivity. As a result, there has been a push in the last fifty years or so to silence some of the annoying sounds that assault people’s ears everyday. While it might seem as simple as covering ones ears, the scientific community has been applying their knowledge in the hope of creating a more peaceful world.
