Welcome to the article The human ear canal is on average 2 5 cm long and aids in hearing by acting like a resonant cavity that is closed on. On this page, you will learn the essential and logical steps to better understand the topic being discussed. We hope the information provided helps you gain valuable insights and is easy to follow. Let’s begin the discussion!
Answer :
The first resonance frequency or first critical speed refers to resonance at a part's native frequency. Higher frequencies, known as the second resonance, are where resonance occurs.
How does the average human ear canal, which is 2.5 cm long and helps with hearing, work?
The human ear canal, which is approximately 2.5 cm long, functions as a resonant cavity which is closed solely on a single end & open on the other to aid in hearing. Our sensitivity to particular frequencies is partially caused by the length of a ear canal.
What is the ear canal's resonance?
With air conduction (AC) excitation, the mean impedance matching of the human middle ear is estimated to be between 0.8 and 1.2 kHz. However ,According to studies, the bone conduction (BC) excitation's mean resonance frequency is higher, at a range of 1.5–2 kHz.
