In higher frequencies, two frequencies can fit into a single bandwidth filter and be selected for. These are called..
Unresolved harmonics
The volley principal
Beats
Residue pitch
Resolved harmonics
Fundamental frequency
Lower frequency sounds require more less double half the same( more, less, double, half, the same ) intensity to be perceived as equal in loudness to higher frequencies.
The physiological mechanism for loudness is proposed to be..
The more neighbouring neurons that are firing together result in the sound being perceived as louder.
The faster the vibrations of the hair cells the louder the sound is perceived.
Stronger activation of a singular tuned cell.
Interaural differences between the ears used to calculate sound levels.
Sound localisation in the Azimuth plane is achieved by..
Interaural time differences
Interaural intensity differences
The shape of the Pinnae
The cone of confusion
Interaural time differences are processed in the Medial Superior Olive. Lateral Superior Olive.( Medial Superior Olive., Lateral Superior Olive. )
Interaural intensity differences are processed in the Lateral Superior Olive. Medial Superior Olive.( Lateral Superior Olive., Medial Superior Olive. )
