Audiometric testing is a hearing assessment used to monitor the hearing health of employees who are regularly exposed to workplace noise. It plays an important role in identifying early signs of hearing deterioration and supporting an effective Hearing Conservation Programme (HCP).
Regular hearing tests help detect changes in hearing ability over time, allowing employers to take appropriate preventive and corrective measures before permanent hearing damage occurs.
Who Requires Audiometric Testing?
Audiometric testing is recommended for employees who are exposed to occupational noise levels that may pose a risk to their hearing. Regular monitoring helps ensure compliance with workplace health and safety requirements while protecting employees' long-term hearing health.
How Is the Test Conducted?
All audiometric assessments are performed by trained audiometric technicians at approved audiometric testing facilities or through mobile on-site audiometry services.
Prior to testing, employees may be required to complete a health screening questionnaire to identify any medical conditions, recent noise exposure, or other factors that could influence the test results.
To ensure accurate results, employees should avoid excessive noise exposure for at least 14 hours before the test whenever possible.
What Does the Test Measure?
The assessment measures hearing thresholds at various frequencies ranging from low to high pitches. Each ear is tested separately using pure-tone air conduction audiometry to determine the employee's ability to hear sounds across different frequencies.
Baseline and Annual Testing
A baseline audiogram is established when an employee first begins work in a noise-exposed environment. This serves as a reference point for future hearing assessments.
Annual audiometric testing is then conducted to compare current hearing levels against the baseline audiogram, allowing any changes in hearing sensitivity to be identified and investigated promptly.
Benefits of Audiometric Testing
Regular audiometric testing supports early detection of hearing loss, compliance with occupational health and safety requirements, monitoring of workplace noise-related risks, protection of employees' long-term hearing health, support for effective Hearing Conservation Programmes, and identification of employees who may require additional hearing protection.
Regular audiometric testing is an essential component of workplace hearing conservation and helps organisations create a safer and healthier working environment for their employees.
