The amount of energy absorbed by the eardrum per second is dependent on the loudness of the sound, and the size of the eardrum. The larger the eardrum, the more energy it can absorb. Additionally, sounds that are lower in frequency will cause the eardrum to vibrate more slowly, and will thus be absorbed more slowly.

Q: How much energy is transferred to the eardrum?
A: There is no definitive answer to this question as the amount of energy transfer to the eardrum will vary depending on a number of factors, including the loudness of the sound, the frequency of the sound, and the distance from the source of the sound. However, it is generally agreed that the eardrum is a relatively efficient transducer of acoustic energy, and that a significant amount of energy can be transferred to the eardrum from even a relatively weak sound source.
Q: How does a sound transfer energy to your ears?
A: Sound waves transfer energy to your ears through the process of vibration. When sound waves hit your ear, they cause the eardrum to vibrate. This vibration is then transferred to the bones of the middle ear, which amplify the sound and send it to the inner ear. The inner ear then converts the sound waves into electrical signals that are sent to the brain, where they are interpreted as sound.
Q: What is the minimum intensity detectable by the human ear?
A: The human ear can detect sound intensities as low as 10 decibels (dB).
