Option 1 â€“ How We Hear This activity explores how we hear andhow the physical nature of the sound wave determines the quality ofthe sound experience. Structure of the Ear What are the three mainregions of the ear and their associated parts? Briefly describewhat happens inside the cochlea? Sound Waves & Frequency Whatare the three aspects of sound waves? Briefly describe each aspect.Which type of tuning fork would vibrate fasterâ€”a small, short oneor a large, long one? How is frequency measured and calculated?Explain why longer sound waves lead to lower frequencies and whyshorter sound waves lead to higher frequencies. The Theory of SoundBriefly describe the three theories relating to how we perceivepitch. Explain why no single theory can explain human perception ofpitch from 20 to 20,000 Hz.

Small short objects vibrate faster than similar objects that are larger or longer The longer produces the top wave the shortwave produces the bottom waves It is measured by counting the number of times the wave goes up down each second When the vibration goes through the middle ear to the cochlea the oval window moves in out which causes the pressure in the outer chamber to increase decrease in a rapid sequence Thealternating high low pressure in the outer chamber produces ripples in the basilar membrane bendsthe hair cells See Answer
