Many employers have failed to follow the Government guidance relating to noise at work. As a result, tens of thousands of employees have had their hearing damaged, either by operating machinery or simply working in a noisy factory. Whilst industrial deafness is usually caused by the repeated exposure to excessive noise, it can be caused by a one time exposure to loud sound.
If the noise to which you were exposed at work was so loud that you had to shout to make yourself heard, then the chances are that your hearing was damaged by your employment. Harmful noise exposure can cause nerve damage or damage to the sensitive hair cells of the inner ear, resulting in deafness or tinnitus (a ringing or whistling in the ears).
Sound is measured in units called decibels. Normal conversation is approximately 60 decibels. Exposure to harmful sounds of about 85 decibels (dB) may be hazardous even if it only lasts for a short period. However, increased decibels and exposure time raise the chances of damage and the damage being more severe. With further exposure to excessive noise, the more the damage can accumulate.
