QuickSIN for Central Auditory Processing Disorder in Patients with Normal Hearing Sensitivity and Reported Speech-in-Noise Difficulty

Overview

Información sobre este estudio

The purpose of this study is to whether the QuickSIN with 0.3 sec reverberation time is a better method than the standard (no reverberation) QuickSIN of detecting central auditory processing disorder (CAPD) in individuals who undergo CAPD evaluations and are diagnosed with CAPD. Also, whether the QuickSIN with 0.3 sec reverberation time is a better method than the standard (no reverberation) QuickSIN at correctly identifying individuals who do not receive a CAPD diagnosis.

 

Elegibilidad para la participación

Los requisitos de elegibilidad de los participantes incluyen la edad, el sexo, el tipo y el estadio de la enfermedad, y los problemas de salud o tratamientos previos. Las pautas difieren de un estudio a otro e identifican quiénes pueden o no pueden participar. No hay garantía de que cada persona elegible que desee participar en un ensayo se inscribirá. Comunícate con el equipo del estudio para analizar la elegibilidad del estudio y la posible participación.

Inclusion Criteria:

  • Normal otoscopic visualization of both ears, including clear external auditory canals and visible tympanic membranes and associated landmarks (e.g., cone-of-light, long arm of manubrium, etc.).
  • Normal pure-tone hearing sensitivity (25 dB HL or better) across all octave frequencies (250 Hz through 8000 Hz) as well as for interoctave frequencies.
  • Tympanometry within normal limits for middle ear pressure (+100 through -150 daPa), tympanic membrane compliance (0.3 through 1.7 mmho), and ear canal volume (0.2 through 2.0 ml), qualified as Jerger Type A tympanograms, in both ears.
  • Ipsilateral and contralateral acoustic reflex threshold patterns that do not indicate the presence of auditory neuropathy spectrum disorder (ANSD). A pattern consistent with ANSD would be elevated and/or absent acoustic reflex thresholds across all conditions and test frequencies in both ears.
  • Present distortion-product otoacoustic emissions (DPOAE) from 1000 Hz through 8000 Hz, bilaterally.

Exclusion Criteria: 

  • Abnormal appearance of one or both external auditory canal(s) and/or tympanic membrane(s) on otoscopic examination.
  • Presence of any degree (mild, moderate, moderately severe, severe, or profound), type (conductive, sensorineural, or mixed), and configuration (shape) of hearing loss.
  • Tympanometry in one or both ears that is abnormal for middle ear pressure (exceeding either +100 or -150 daPa), tympanic membrane compliance (below 0.3 or above 1.7 mmho), and/or ear canal volume (less than 0.2 or greater than 2.0 ml). This includes tympanograms described as As, Ad, B, and C.
  • Ipsilateral and contralateral acoustic reflex threshold patterns that indicate the presence of ANSD (i.e., elevated and/or absent acoustic reflex thresholds across all conditions and test frequencies in both ears).
  • Absent DPOAEs for any frequency measured between 1000 Hz through 8000 Hz for either ear.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
