विकल्प

• Significant change in pulse rate

• Permanent damage to hearing

• Nausea, vomiting, dizziness

Answer 1

Significant change in pulse rate

Explanation:

At 150 dB, the noise level is extremely high and can cause significant physiological changes, such as a significant change in pulse rate. This is due to the body's stress response to such intense sound, leading to an increase in heart rate and blood pressure. Prolonged exposure can also result in other health issues like hearing damage, nausea, and dizziness. However, the most immediate effect is the change in pulse rate due to the body's reaction to the stress.
