Fundamental pitch?Read the answer and worked solution →A string's other properties stay fixed. Raising tension makes its pitch?Read the answer and worked solution →Opening flute finger holes chiefly changes the effective?Read the answer and worked solution →A vibrating source completes 450 oscillations in 3 seconds. Frequency?Read the answer and worked solution →A 250 Hz source vibrates for 0.2 seconds. Complete oscillations?Read the answer and worked solution →Flute and guitar have 200 Hz fundamentals. Their fundamental pitches?Read the answer and worked solution →A drum's frequency stays fixed as amplitude rises. What changes?Read the answer and worked solution →As a tone fades, its pitch stays fixed. It remains?Read the answer and worked solution →To test length's effect on string pitch, keep which properties fixed?Read the answer and worked solution →Longer and tighter, but the same mass per metre: how does a string's pitch change?Read the answer and worked solution →Shorter, lighter-per-metre string; same tension. Fundamental pitch?Read the answer and worked solution →Frequency doubles; amplitude is unknown. What follows?Read the answer and worked solution →

Order how sound reaches your brain

Read exercise and reference answers
Steps
  1. A vibrating object creates a disturbance in the air
  2. The disturbance travels as a longitudinal wave
  3. The wave reaches your ear and vibrates the eardrum
  4. Tiny bones amplify the vibration to the inner ear
  5. Nerve signals reach the brain, which interprets sound
Instructions
Tap the stages in order, from a vibrating object to the sound your brain finally hears.

In a guitar, which part is plucked to start sound production?

  1. A hollow air column
  2. A stretched membrane
  3. A stretched string
  4. A vibrating reed
Show answer and solution

Correct answer: C. A stretched string

Plucking sets a guitar's stretched string into vibration.

Which vibrating part produces sound when a tabla is struck?

  1. A stretched string
  2. A stretched membrane
  3. An elastic metal reed
  4. A blown air column
Show answer and solution

Correct answer: B. A stretched membrane

A tabla produces sound through vibration of its stretched membrane.
