Question
Chapter 44, Problem 4TY
Summary Introduction
Introduction: Statocysts are the sensory organs present in animals which helps in detection of gravity. These organs send the signal to the brain which tells brain about the position of the animal.

Which of the following are correct?
Which one or more?
a.
Auditory fatigue is the increase in threshold after exposure to a loud sound. Auditory adaptation is a reduction in response of the auditory receptors to a sound over time followed by a steady state.
b.
The change in auditory thresholds is independent of the intensity, but dependent on the duration of the loud sound.
c.
Exposure to loud sounds is unable to damage the hair cells in the inner ear and therefore cannot lead to a permanent threshold shift.
