Which type of hazard can lead to permanent or temporary deafness?

Pneumonia
Noise
Heat exposure
Vibration

The correct answer is: Noise

The correct choice relates to noise as a type of hazard that can lead to both permanent and temporary deafness. Prolonged exposure to high levels of noise can damage the sensitive structures of the inner ear, leading to hearing loss. The threshold for damage commonly depends on both the intensity of the noise and the duration of exposure. In occupational settings, this means that workers in environments with high decibel levels, such as factories or construction sites, are at risk if appropriate protective measures are not implemented. Temporary threshold shift can occur after exposure to loud sounds, where hearing may return to normal after a period of rest, but with repeated exposure, this can escalate to permanent damage known as Noise-Induced Hearing Loss (NIHL). Understanding the risks associated with noise is critical for the implementation of effective health and safety practices to protect workers' auditory health. This includes strategies such as using hearing protection devices and minimizing noise exposure duration. Other options, while they represent different types of health risks, do not specifically lead to hearing-related issues directly caused by exposure to hazardous levels of sound.
