Effect of audibility on spatial release from speech-on-speech masking.
This study investigated to what extent spatial release from masking (SRM) deficits in hearing-impaired adults may be related to reduced audibility of the test stimuli. Sixteen adults with sensorineural hearing loss and 28 adults with normal hearing were assessed on the Listening in Spatialized Noise-Sentences test, which measures SRM using a symmetric speech-on-speech masking task. Stimuli for ...
متن کاملSpeech intelligibility and spatial release from masking in young children.
Children between the ages of 4 and 7 and adults were tested in free field on speech intelligibility using a four-alternative forced choice paradigm with spondees. Target speech was presented from front (0 degrees); speech or modulated speech-shaped-noise competitors were either in front or on the right (90 degrees). Speech reception thresholds were measured adaptively using a three-down/one-up ...
متن کاملSpatial release from masking with noise-vocoded speech.
This study investigated how confusability between target and masking utterances affects the masking release achieved through spatial separation. Important distinguishing characteristics between competing voices were removed by processing speech with six-channel envelope vocoding, which simulates some aspects of listening with a cochlear implant. In the first experiment, vocoded target nonsense ...
متن کاملRole of binaural hearing in speech intelligibility and spatial release from masking using vocoded speech.
A cochlear implant vocoder was used to evaluate relative contributions of spectral and binaural temporal fine-structure cues to speech intelligibility. In Study I, stimuli were vocoded, and then convolved through head related transfer functions (HRTFs) to remove speech temporal fine structure but preserve the binaural temporal fine-structure cues. In Study II, the order of processing was revers...
متن کاملFactors affecting masking release in cochlear-implant vocoded speech.
Cochlear-implant (CI) listeners generally perform better when listening to speech in steady-state noise than in fluctuating maskers, and the reasons for that are unclear. The present study presents a new hypothesis for the observed absence of release from masking. When listening to speech in fluctuating maskers (e.g., competing talkers), CI users cannot fuse the pieces of the message over tempo...
