"First Mobile Audiometric Service Provider in Sarawak"
OUR TEAM COMPRISING OF QUALIFIED AUDIOMETRIC TESTERS, OCCUPATIONAL HEALTH DOCTOR & EXPERIENCED TECHNICIANS
Global Green OSH Services Sdn Bhd, specializing in providing the first mobile medical services for most industries in Sarawak. As a FIRST company that pioneered such mobile services, we focus mainly on mobile Audiometric Testing programme as well as mobile Medical Surveillance programme on-site.
In most industries, long exposure to excessive noise create a potential noise hazard to worker where noise-induced hearing loss being the major concern if not carefully controlled. The objective of Social Security Organisation of Malaysia (SOCSO) is to ensure and guarantee the timely and adequate provision of benefits in a socially just manner and to promote occupational health and safety which includes occupational diseases related of employment injury compensation, prevention and rehabilitation. Among all forms of occupational diseases, loss of hearing due to exposure to continuous excessive noise being one of the most reported cases.
Audiometric evaluation is essential to the success of the hearing conservation program (HCP) in that it is the only way to determine whether noise-induced hearing loss is being prevented. When the comparison of audiograms shows temporary threshold shift (temporary deafness lasting from seconds to hours), early permanent threshold shift, or progressive noise-induced hearing loss, it is time to take swift action to halt the loss before additional deterioration occurs.
Often industrial worker will not notice the change of noise-induced hearing loss as it happens gradually and not accompanied by immediate pain. Additionally, most workers did not aware that exposing their ear to noise levels of about 85dBA for even a few minutes may induce a temporary deafness. By establishing the results of audiometric tests, it can initiate the protective measures on motivating employees to prevent further hearing loss. The audiometry provides an audiogram which is a measure over a range of frequencies, of the threshold of hearing at which sound can just be detected. Early deafness occurs in the frequency range 2-6 kHz and is shown typically as a dip in the audiogram at 4 kHz.
The depth of the dip depends on the degree of hearing damage and, as this worsens, so the loss of hearing widens to include neighboring frequencies. In summary, the advantages of an audiogram are that it:
a) Provides a baseline for future comparison;
b) Is helpful in job placement; and
c) Can be used to detect early changes in hearing and in the diagnosis of noise-induced deafness.
