Title: Perception of Iranian musical phrase in patients with cochlear implantation

Abstract

Background: Cochlear implantation (CI) has

successfully provided speech perception for

patients with sensorineural-hearing loss, but the

perception of music has always been limited for

them.

Methods and Materials: We sought to investigate

adult CI users’ ability in differentiating the pitch

and perception of melody in Amir Alam Hospital.

The possible effect of background variables in this

regard was also investigated. Data were collected

using a questionnaire and a music test, which

includes the following four sections: 1, The

slightest pitch perception; 2, Ability to differentiate

two melodies by one-octave distance; 3, Ability to

differentiate rhythmic melodies from non-rhythmic

ones; and 4, Ability to differentiate between two

Iranian phrases of Mahoor and Shour.

Results: Twenty CI users with the mean age of

21.7 ± 2.9 were evaluated. Of these, 10 received

professional musical training, and 9 played an

instrument. The shortest distance of pitch

perception between two tones in 5(28.2%) was a

quarter-tone, in 8(44.4%) was half-tone, in

4(22.2%) was a tone, and in 1(5.6%) was 3-tones.

All participants distinguished two melodies with

one-octave interval, 94% of rhythmic melodies

from non-rhythmic ones, and 76% of individual

differentiate Mahoor and Shur phrases. Among the

factors studied, the duration of deafness,

inclination to classical western music, having

musical training, playing an instrument, and

duration of daily playing affected the ability to

understand the quarter-tones. Moreover, the ability

to differentiate between Mahoor and Shur phrases

was significantly dependent on the quarter-tone

perception.

Conclusions: We showed that CI users had an

extreme desire for music. As a result of this

tendency, they have an excellent ability to

differentiate the pitch of short-distance sounds,

which has made it possible for many of them to

perceive the slight differences between the Mahoor

and Shur phrases.
