Evaluating Music Perception of Cochlear Implant Users:

Information for Audiologists

Speech versus Music

1, 2

How does the perception of music compare with speech? 

  • Both music and speech are made up of dynamic multifaceted patterns of frequency, duration, spectrum, and amplitude. 

    • Speech can be broken down into components such as consonants and vowels, phonemes, and words.  

      • These components are connected to form phrases, sentences, and paragraphs.

    • Music can be broken down into components of such as pitches, timbres (specific vocal or instrumental tone quality), rhythm.

      • These components together make up melodic, harmonic, and rhythmic patterns;

      • These components are connected to comprise compositions or music improvisations.

  • Perceptual requirements for speech and music via electric hearing are different. 

    • Cochlear implants convey the temporal envelope of the auditory signal; CIs do not convey the fine structure (spectral complexity) of the signal.

    • Speech

      • Segmental speech components can be perceived fairly accurately from the temporal envelope. 

      • Suprasegmental features of speech (such as emotional or lexical prosody) require a more fine structure.

    • Music 

      • The rhythm of music can be perceived effectively through the temporal envelope.

      • Pitch and timbre perception in music requires greater fine structure. 

 

How does testing of music compare with testing of speech? 

  • Both music and speech are complex forms of communication; no single test can capture all aspects of either speech or music. 

    • Music and speech testing should assess the perception of isolated structural components as well as a larger unit of connected music or speech.

      • Perception of isolated units of sound does not fully predict accuracy on connected real-world listening tasks.

    • Testing should include a variety of response tasks:

      • detection, discrimination, identification, comprehension

      • open set vs. closed set

      • with or without non-auditory cues (visual, tactile, context)

    • Music testing may include tests of appraisal (appreciation, enjoyment) as well as perceptual accuracy. 

      • Perceptual accuracy is not highly correlated with music appreciation/enjoyment (Gfeller et al., 2008). 

        • Because people listen to music for pleasure, sound quality is a key concern for music perception. 

      • Both speech and music occur within the cultures of CI users, therefore testing needs to take into account the cultural and experiential background of those being tested.  

        • Music known to CI users from one country (e.g., the United States) may not be familiar to CI users from other countries (e.g., Korea). 

      • ​Some tests are more relevant to evaluating the technical features of the internal array or signal processing. 

      • Some tests are more relevant to evaluating the functional benefit of CIs for real-world musical or spoken communication. 

  • Important differences in speech and music that affect testing:   

    • Words are made up of a letter or groups of letters that have specific meanings; musical notes do not.

      • For example, CI users could listen to the word, 'bed' and repeat the word or provide a definition. Most CI users or normal-hearing listeners would be unable to name the notes, 'B  E  D' even if they can perceive the pitches accurately. 

      • Many CI users would be unable to relate the sound of the notes to notation. Musical notes are self-referring---they do not refer to an object or idea. 

"Bed" in speech vs. "Bed" in musical notation

  • Most adults have learned to read written language as part of their basic education; literacy for musical notation is not evenly distributed. 

    • Not all CI users would be able to listen to music and relate the sounds to musical notation. 

  • Words are combined into phrases, sentences, paragraphs to convey specific thoughts, beliefs, feelings; music does not express specific concepts, but is associated with communicating emotions and aesthetic beauty and enjoyment. 

    • The extent to which a musical sound is pleasant is an important aspect of music perception. 

    • Different people find different kinds of music enjoyable.

    • Perceptual accuracy does not guarantee enjoyment; a person may perceive music very accurately but still find the sound unpleasant. (Wright & Uchanski, 2012) 

    • Some CI users have a poor perception of pitch and timbre,  yet they still enjoy listening to music.  

  • Spoken words have more limited frequencies, spectral characteristics, and dynamics than music. 

  • Speech is usually organized around one person talking at a time.  Music is often made up of multiple notes playing at the same time,  sometimes by many different instruments or voices. 

  • Cochlear implants have been designed to convey those features of speech most salient to understanding.  Pitch and timbre, two key features of music, are not accurately represented by signal processing.

Evaluation of Music Listening includes 1) perceptual accuracy and 2) appraisal. 

Perceptual accuracy: Compares CI users with normal hearing listeners on different structural components of music. Examples of outcomes include: 

  • Perception of isolated components (pitch, duration, timbre, dynamics)

    • Discrimination: are two sounds or patterns of notes (pitch, rhythm, timbre, dynamics) the same or different? 

    • Is one pitch higher or lower than another? 

    • Do note patterns (melodic contours) go higher, lower, or stay the same? 

    • Can you recognize what musical instrument you are hearing (e.g., a piano or violin?)

    • Can you tell the difference between a male and a female singer?

    • Can you recognize different types of musical ensembles?

  • Perception of connected or real-world musical excerpts

    • Can you recognize a familiar song (e.g., "Happy Birthday," "Hound Dog")

    • Rating of the complexity of the musical segment

    • Can you repeat the lyrics in a song? [with or without accompaniment]

Appraisal: How pleasant or natural music sounds through a CI compared with normal hearing.

  • This is not the same as musical taste or preference (e.g., what style of music is preferred).  The appraisal may be of isolated musical features (e.g., single notes from different instruments) or connected or real-world musical excerpts. 

  • How natural does the music sound? Assigning numbers (ratings)

  • Bi-polar adjectives of sound quality (e.g., thin-full; rough-smooth; natural-unnatural).

  • Multidimensional scaling

  • How pleasant (Likert scales, rating scales)

  • How much time do you listen to music after the CI? 

 

What to look for in a music test:

  • The tasks are appropriate for the age of the individual. 

  • The tasks are appropriate for the onset of hearing loss and age at implantation. 

  • The characteristics and results of the test appear in articles in reliable journals. 

  • The tests discriminate among CI users on accuracy and/or enjoyment. 

  • The tests discriminate between CI users and listeners with normal hearing. 

  • The test is valid in measuring particular research or clinical construct.

 

Many references at the end of this webpage describe tests used in experiments, as measures of music training efficacy, or published tests for various aspects of music perception and appraisal. This list is not comprehensive, nor is it an endorsement of any particular tests.
