- Occupational Hearing Loss Frequent exposure to loud noise of a particular pitch can cause loss of hair cells in the part of the cochlea that responds to that pitch. People who work with or around noisy machinery are at risk for such frequency-specific hearing loss. Taking precautions such as using ear plugs to reduce sound exposure is important. Noise-induced hearing loss can be prevented, but once it occurs it is irreversible because dead or damaged hair cells are not replaced. FIGURE 33.24 shows the threshold decibel levels at which sounds of different frequencies can be detected by an average 25-year-old carpenter, a 50-year-old carpenter, and a 50-year-old who has not been exposed to on-the-job noise. Sound frequencies are given in hertz (cycles per second), The more cycles per second, the higher the pitch. FIGURE 33.24 Effects of age aria occupational noise exposure. The graph shows the threshold hearing capacities fin decibels) for sounds of different frequencies (given in hertz) in a 25-year-okj carpenter (blue). a 50-year-old carpenter (red), arid a 50-year-ofd who did not have any on-the-job noise exposure (brown). 1.

- A major function of the middle ear is to transmit sound vibrations from the external ear to the inner ear. Use words and arrows to make a flow-chart (words with arrows) that depicts the middle ear structures in the order in which sound vibrations are passed as they make their way from the tympanic membrane to the inner ear.arrow_forwardExplain briefly the signal transduction for the following senses: i. Hearing. ii. Vision.arrow_forwardExplain the nature of sound, and describe how it travels through the various parts of the ear.arrow_forward
- All sensory organs convert energy in the environment into action potentials in the nervous systern. Explain the process of how our ears convert energy in the form of sound waves in the air into action potentials along a nerve. Include the appropriate order of structures and regions of the ear as well as the physiological process of creating action potentials and interpreting them in the brain.arrow_forwardDefine and describe the structure, location, and innervationpathway of gustatory receptors.arrow_forwardName the audio receptors present in the human ear.arrow_forward
