The correct Answer is:
To solve the question "The quietest sound that the ear of a man can detect is known as," we will analyze the options provided and determine the correct answer step by step. ### Step-by-Step Solution: 1. **Understanding the Question**: - The question is asking for the term that describes the quietest sound detectable by the human ear. 2. **Evaluating the Options**: - **Option 1: Acoustic Zoning**: - This term refers to the classification of areas based on their environmental noise levels. It does not relate to the detection of sound by the human ear. - **Conclusion**: This option is incorrect. - **Option 2: Threshold of Hearing**: - This term refers to the minimum sound level that can be detected by the human ear. It is defined as the quietest sound that a person can hear. - **Conclusion**: This option is likely correct. - **Option 3: Threshold of Pain**: - This term describes the sound level at which sound becomes painful for the ear, typically above 110 decibels. It is not related to the quietest sound detectable. - **Conclusion**: This option is incorrect. - **Option 4: Green Muffler**: - This refers to vegetation used to absorb noise, such as trees and shrubs. It does not pertain to sound detection by the human ear. - **Conclusion**: This option is incorrect. 3. **Final Decision**: - After evaluating all the options, the only term that accurately describes the quietest sound detectable by the human ear is **Threshold of Hearing**. ### Answer: The correct answer is **Threshold of Hearing**. ---

The faintest sound the human ear can detect at a frequency of 1000 Hz correspond to an intensity of about 1.00xx10^-12(W)/(m^2) , which is called threshold of hearing. The loudest sounds the ear can tolerate at this frequency correspond to an intensity of about 1.00(W)/(m^2) , the threshold of pain. Detemine the pressure amplitude and displacement amplitude associated with these two limits. Take speed of sound =342(m)/(s) and density of air =1.20(kg)/(m^3)

The faintest sound the human ear can detect at a frequency of 1kHz (for which the ear is most sensitive) corresponds to an intensity of about 10^(-12)W//m^2 (the so called threshold of hearing). Determine the pressure amplitude and maximum displacement associated with this sound assuming the density of air = 1.3kg//m^2 and velocity of sound in air = 332 m/s

The faintest sound the human ear can detect at a frequency of kHz (for which ear is most sensitive) corresponds to an intensity of about 10^(-12)w//m^(2) . Assuming the density of air cong1.5kg//m^(3) and velocity of sound in air cong300m//s , the pressure amplitude and displacement amplitude of the sound will be rspectively ____ N//m^(2) and ____ m .
