Noise-Induced Hearing Loss (NIHL) Test in Johor Bahru

Ujian Kehilangan Pendengaran Akibat Bising (NIHL)

Noise-induced hearing loss (NIHL) is one of the most common occupational diseases among factory and industrial workers in Pasir Gudang and the greater Johor Bahru industrial belt. Klinik Muhibbah provides DOSH-compliant NIHL audiometry testing required under OSHA 1994 for workers exposed to noise levels above 85 dB(A). Our OHD NIOSH certified doctor Dr. Prabagaran interprets audiograms, identifies early NIHL patterns, and issues legally valid employer reports. Baseline and annual follow-up audiometry are both available.

How to Prepare

📝

Workers must avoid occupational noise exposure for at least 14 hours before testing — this means no work in noisy areas the night before. Do not use earplugs or earphones in the hours before testing. Inform our staff of any ear infections, tinnitus, or ear surgery history. Employers booking group tests should provide a worker list in advance.

Frequently Asked Questions

Which factories in Pasir Gudang need to arrange NIHL audiometry for workers?▼
Any workplace where noise levels exceed 85 dB(A) time-weighted average (TWA) is legally required to arrange annual audiometry under OSHA 1994 and USECHH Regulations. This includes manufacturing plants, fabrication yards, printing facilities, and food processing factories. Klinik Muhibbah serves the entire Pasir Gudang industrial area — call for group booking and competitive corporate rates.
What does an NIHL audiogram look like and how is it diagnosed?▼
NIHL produces a characteristic dip (notch) in hearing threshold at 4000 Hz on the audiogram — often called the 4 kHz notch. Our OHD doctor identifies this pattern, grades the severity of hearing loss, and classifies it as noise-induced versus age-related or other causes. Early detection allows intervention before hearing loss becomes severe.
Can noise-induced hearing loss be reversed?▼
Unfortunately, established NIHL is permanent and irreversible — damaged cochlear hair cells do not regenerate. However, early detection allows immediate protective measures to prevent further progression. This is why annual audiometry monitoring is so important — catching workers with early hearing changes before they progress to disabling hearing loss.
