Question

what are some effects of exposure to noise? (check all that apply)

a elevated blood pressure
b increased heart rate
c hearing loss
d changes to hormonal levels in the blood

Explanation:

Analyze physiological and auditory effects of noise exposure

• Auditory effects: Chronic or acute exposure to high decibel levels directly damages the hair cells in the cochlea, leading to temporary or permanent hearing loss.
• Non-auditory physiological effects: Noise acts as a general biological stressor, triggering the sympathetic nervous system (fight-or-flight response). This response releases stress hormones (such as cortisol and adrenaline) into the bloodstream, which subsequently elevates heart rate and blood pressure.

Evaluate the given options

• Option A (Elevated blood pressure): Correct, caused by stress-induced vasoconstriction.
• Option B (Increased heart rate): Correct, caused by sympathetic nervous system activation.
• Option C (Hearing loss): Correct, direct physical damage to the auditory system.
• Option D (Changes to hormonal levels in the blood): Correct, triggers release of stress hormones like cortisol and adrenaline.

Answer:

• (A) Elevated blood pressure (Correct answer)
• (B) Increased heart rate (Correct answer)
• (C) Hearing loss (Correct answer)
• (D) Changes to hormonal levels in the blood (Correct answer)
