Question 10 of 15
10. Question
Match the label to the description below.
Description
- Individuals may be more susceptible to the effects of noise – The effects of noise on the vestibular apparatus could affect the sense of balance resulting in dizziness and poor balance which has a knock-on effect on safety in the workplace.
- The loss is usually greater that 70dB
- The rate of hearing loss is greatest during the first 10-15 years of exposure and decrease as the hearing threshold increase
- No significant air-bone gap and hearing loss is mostly seen in the higher frequencies
- The maximum threshold loss is not usually more than 60 – 70dB
- Moderately Severe Hearing Loss
- Refers to the degree and pattern of hearing lossacross frequencies (tones) in an audiogram
- Hearing Loss between 26 – 40dBs
