About this study
Official title: Relationship Between Pitch Discrimination, Music Abilities and Emotional Speech Perception in School Aged Children With Cochlear Implant
The investigators evaluated patients older than 6 years old, with severe hearing loss, cochlear implant wearers, able to perform a series of tests (TUISE, the pitch discrimination test, the melody discrimination test, VAS) to assess the skills of perceiving spectral components of music and understanding emotional states of language investigating the relationship between musical ability, pitch discrimination and paraverbal language comprehension.
Read the detailed description
The investigators evaluated patients with severe hearing loss, undergoing cochlear impantation, to assess the skills of perceiving spectral components of music and understanding emotional states of language.
Each patient will undergo:
- Music test: a battery of music tests has been designed to assess CI-mediated music perception. The software will be installed on a computer, which is normally used to adapt patients' maps in routine adaptation sessions. It consists of two parts: A) the pitch discrimination test; B) the melody discrimination test
- In the pitch discrimination test, the stimuli consist of pairs of notes played by a piano and spaced at least one semitone apart, semitone being the smallest interval in traditional Western music. The notes are distributed within the middle three octaves (C4, C5, C6, each corresponding to the following frequency bands: 262 Hz-523 Hz, 523 Hz-1046 Hz, and 1046 Hz- 1976 Hz), used for most of the pieces, for a total of 36 notes. After listening to each pair of notes, the patient is asked to indicate whether they are the same or different in pitch. It consists of seven levels of increasing difficulty determined by the reduction in the distance between notes: the 1st level included pairs of notes 12 semitones apart (easiest task), while the 7th level included notes one semitone apart (most difficult task). Each level is further divided into two tests: TEST A: consisting of two parts (each of 10 questions) in which the subject must choose between 2 notes belonging to the 5th and 6th musical octaves (523-1976 Hz). TEST B: consists of two parts (each of 10 questions) in which the subject must choose between 2 notes belonging to the 4th and 5th musical octaves (262-988 Hz). In the last 2 levels (6th and 7th levels) there are 20 more questions investigating discrimination on the middle (related to the 5th octave). At the end the score of each level will be calculated (as the percentage of correct answers) and the final total score.
- The melody discrimination test consists of 6 popular cartoon songs in digital recording, synthesized with Finale™ 2008 (MakeMusic Inc., Eden Prairie, MN). Before the test performance, subjects will be asked to watch a 30-second cartoon scene and memorize the corresponding song from an IBM© laptop (IBM, Armonk, USA). Each song will be presented twice, for a total of 12 entries. The music test is divided into two sessions: in session 1, full version songs (instrumental plus vocal) for a total of 6 voices. Patients will indicate the distinctive character on the screen for each song. In session 2, songs in melodic version, presented in random order for a total of 6 musical items. An overall score will be calculated based on the correctly identified elements.
- TUISE test (Auditory Test Identifying Emotional States): the Auditory Test of Identifying Emotional States (T.U.I.S.E.) is a new instrument to assess emotional states. It consists of 4 subtests, each consisting of 15 questions. Each item involves an audio recording of short sentences spoken with varying intonation by different readers of both sexes. To ensure proper administration, all background noise was removed and semantically neutral sentences were chosen. In addition, a glossary was developed with explanations and examples for all the emotional states presented. In the 1st subtest, the task is to identify among the four basic emotions (happy, sad, angry, scared) which one best described the speaker's emotional state (only one term, among the four words, correctly represented what the speaker was thinking or feeling). In the 2nd subtest, more complex emotions are assessed as patients have to identify among four terms regarding complex emotional states varied for each item, the one that correctly expressed the emotional state expressed by the speaker (joking, doubtful, agitated, rude, concerned, friendly, bored, excited, hopeful, surprised, overbearing and angry). In the 3rd subtest, which required speaker discrimination, each item consisted of two recordings. They are, in fact, presented with several pairs of vocal traces, and the patient has to distinguish whether each item is presented by different people or not. Finally, the 4th subtest consists to identify the gender of the speaker. Each item consists of an audio track and the patient have to mark whether the speaker is male or female.
- Visual analog scale (VAS scale): it is used to estimate, with a score from 1 to 10, how pleasant it is to listen to music.
The aim is to investigate the relationship between musical ability, pitch discrimination and paraverbal language comprehension.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pitch discrimination test
The stimuli consist of pairs of notes played by a piano and spaced at least one semitone apart, semitone being the smallest interval in traditional Western music. The patient is asked to indicate whether they are the same or different in pitch. It assesses discriminative skills
Measured: 6 months after cochlear implantation
Melody discrimination test
Consists of 6 popular cartoon songs in digital recording. Subjects will be asked to watch a 30-second cartoon scene and memorize the corresponding song. In session 1, full version songs (instrumental plus vocal) for a total of 6 voices. Patients will indicate the distinctive character on the screen for each song. In session 2, songs in melodic version, presented in random order for a total of 6 musical items. It assesses discriminative skills

Questions about this trial
What is this clinical trial studying?
An observational study of Hearing Loss, Sensorineural, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
