Major Health

Noise-Induced Hearing Loss (NIHL) has become a major health threat to the Malaysian industrial workers in the recent era due to exposure to high frequency noise produced by the heavy machines. Recently, many studies have been conducted to diagnose the NIHL in industrial workers but unfortunately they neglected some factors that can play a major role in speeding-up NIHL. In this paper, a new Hybrid Bat-BP algorithm which is based on the trio combination of BAT based metaheuristic optimization, back-propagation neural network, and fuzzy logic is proposed to diagnose NIHL in Malaysian industrial workers. The proposed Hybrid Bat-BP will use heat, body mass index (BMI), diabetes, and smoking along with the century old audiometric variables (i.e. age, frequency, and duration of exposure) to better predict NIHL in Malaysian workers. The results obtained through Hybrid Bat-BP will be able to help us identify and reduce the NIHL rate in the workers with high accuracy.

Discharge Rates

The spontaneous discharge rates of auditory nerve fibers were measured in a group of normal chinchillas and in a group of chinchillas with high-frequency, noise-induced hearing loss. In contrast to normal units, the high-frequency units in the noise-exposed animals tended to have elevated spontaneous discharge rates, high thresholds, and a lack of two-tone inhibition. The change in spontaneous discharge rate across the distribution of nerve fibers is related to models of tinnitus and to human psychophysical data.

Comfortable Loudness

Temporal resolution, or the ability to process rapidly changing stimuli, has been purported to be reduced in some listeners with hearing loss while being described as normal in others. Ensuring stimulus audibility by increasing stimulus levels results in near-normal temporal resolution abilities for many listeners with hearing loss, but may also result in uncomfortably loud stimulus levels. The current study was conducted to describe temporal resolution abilities of listeners with and without hearing loss as a function of stimulus loudness. The gap detection abilities of 8 listeners with normal hearing were compared with those of 8 listeners with mild to moderate hearing losses over a wide range of intensities using a 650-Hz wide high-frequency noise marker. At low intensities, listeners with hearing loss show poor gap detection ability. As intensity increases, most listeners’ performance improves and stabilizes near normal at high loudness and sensation levels. At comfortable loudness, gap detection abilities of listeners with hearing loss are less than at loud levels and are considerably poorer than normal.
