INTRODUCTION Noise is a global problem that is widespread across varying occupations. This is evident in statistics provided by Centre for Disease Control and Prevention (2015) showing farmers in Poland are exposed to a mean level of 98.1 dB, textile workers in Nigeria were exposed to a 130 dB, an average exposure of 91.9 dB for persons in music clubs in the US with airport employees in China having abnormal audiograms reflecting 41% prevalence rate of hearing loss in high frequencies. Noise-induced hearing loss is insidious, permanent, and irreparable.

and Henderson, D. (2011) categorically states that noise measurement has to be done in accordance with standard operating procedures and ensured that they are matched against evaluated criteria to be deemed suitable. The detailed noise survey 's aim is to establish whether or not the workplace contains noise that exceeds the exposure limits. Monitoring in the general environment using a calibrated sound level meter was done firstly followed by personal monitoring. In areas where the general monitoring indicated that the exposure equals to or was above 90 dBA a calibrated personal dosimetric test was conducted. Further information was gathered through an interview/questionnaire with details of the employee’s job description, recreational activities and personal demographics. All the employees who were exposed to noise levels equal to or in excess of 90 dBA on an 8-hour time weighted average was included in the Hearing Conservation Program. Futuristically, the areas where the noise levels dropped below 90 dBA because of changes in equipment or other control measures, the areas and employees would be removed from the monitoring

  • The Use Of Cochlear Implants In True Biz By Sara Polish

    531 Words  | 3 Pages

    Sara Nović’s novel True Biz is, at its core, a depiction of the struggle between the Deaf community and its hearing counterpart. Much of the book is spent describing how hearing people who fail to understand the Deaf community have mainstreamed their deaf children through the use of ASL deprivation and the use of cochlear implants. Nović feels pride about the Deaf community and wants to teach us about it so that we in the hearing world can better help to prevent its destruction. Unfortunately, in doing this, Nović has painted a one-sided picture regarding the use of cochlear implants by failing to include examples of successful ones, her depiction of Austin's family struggle around the issue, and most importantly, by glorifying the destruction of the bionics lab.

In Australia between nine and 12 children per 10,000 births will be born with a moderate or greater hearing loss in both ears and a further 23 children per 10,000 will acquire a hearing impairment that will require hearing aids by the age of 17 (Australian Hearing 2013). Within the Aboriginal and Torres Strait Islander communities it is estimated that 30-80% of indigenous children will suffer from some form of hearing loss. Ear disease and hearing impairments is a significant problem in developing countries and among many of the indigenous populations, especially in Australia (Burrow et al. 2009). Although middle ear disease or Otitis Media (OM), an inflammation of the middle ear, typically leads to conductive hearing loss there are rare cases leading to high frequency sensorineural hearing loss after repeated exposure (Burrow et al. 2009; American Speech-Language-Hearing Association [ASLHA]

One way that they enforce this is the use of various handicaps, one being earpieces. One protagonist, George Bergeron is described as having a higher than average intelligence.
