[blank_start]Frequency[blank_end]: how many waves in a second? Corresponds to [blank_start]pitch[blank_end]. [blank_start]Amplitude[blank_end]: how high is the wave? Corresponds to [blank_start]loudness[blank_end]. [blank_start]Phase[blank_end]: how far through the wave are we? Corresponds to [blank_start]tibre[blank_end].

In complex sounds, the component with the [blank_start]lowest[blank_end] frequency is called the 'fundamental'.

If a filter is linear it follows the rules:

Select the reasons out ear could be considered a Fourier Analyser.

Outer Ear: [blank_start]pinna[blank_end], [blank_start]meatus[blank_end] Middle Ear: [blank_start]ossicles[blank_end], [blank_start]tympanic membrane[blank_end] Inner Ear: [blank_start]cochlea[blank_end]

How many hair cells protrude from the basilar membrane?

Parts of the wave where air pressure is increased are called [blank_start]compressions[blank_end]; parts where the pressure is decreased are called [blank_start]rarefactions[blank_end].

The inner ear contains mechanoreceptors for:

The chambers in the cochlea are the:

Phase locking is important for:

An auditory nerve fibres response to a tone during the presentation of a second tone is

The [blank_start]Superior[blank_end] Olive contains binaural neurons that provide information about the location of sound sources.
