A dichotic pitch can be perceived due to the binaural presentation of white noise with a particular interaural phase relationship. Three perceptual aspects are characteristic: the pitch value, the timbre of the phenomenon, and the lateralized position of the pitch image. As dichotic pitch phenomena are generally considered to be natural epiphenomena of the mechanisms of binaural hearing, infere...

ITU recommendation P.862, PESQ was developed for measuring speech quality in a wide variety of conditions. This paper shows that PESQ can also be used for measuring speech intelligibility. An experiment was set up to evaluate speech intelligibility in the presence of two interfering talkers at 4 SNR conditions (0, -3, -6, and -9 dB), using 100 sentences in each condition, with five normal heari...

Today's audiological functional diagnostics is based on a stock of hearing tests, whose large number takes account of the variety of malfunctions of a complex sensory organ system and the necessity to examine it in a differentiated manner and at any age of life. The objective is to identify nature and origin of the hearing loss and to quantify its extent as far as necessary to dispose of the in...

Purpose: To develop Brazilian Portuguese Dichotic Sentence List Test, check its applicability and propose an application protocol for auditory processing assessment. Methods: The lists of sentences were taken from the original material, analyzed in detailed and adapted to form the new test. To compose pairs of sentences with as much of the same duration as possible, the duration of each sentenc...

background and aim: spatial hearing is one of the most important functions of binaural hearing processing that is based on detection of fine interaural time and interaural intensity difference. spatial hearing is beyond auditory localization and lateralization. it helps auditory scene analysis and target stream segregation from other simultaneous sound sources. this function is important in spe...

Purpose: To compare the performance of the Dichotic Sentence Identification (DSI) test in the Brazilian Portuguese version, considering: the right and left ears and the educational status in normal-hearing individuals. Methods: This investigation assessed 200 individuals who are normal listeners and right-handed and were divided into seven groups according to the years of schooling. All the par...

OBJECTIVES The purpose of the study was to examine recognition of degraded melodic stimuli in dichotic listening with or without frequency-place mismatch. DESIGN Melodic stimuli were noise vocoded with various number-of-channel conditions in a dichotic and monaural processor. In the dichotic zipper processor, the odd-indexed channels were tonotopically matched and presented to the left ear wh...

Older adults with sensorineural hearing loss have greater difficulty understanding speech than younger adults with equivalent hearing (Gates & Mills, 2005). This increased difficulty may be related to the influence of peripheral, central auditory processing or cognitive deficits and although this has been extensively debated the relative contribution to speech understanding is equivocal (Workin...

A survey of auditory processing (AP) diagnostic practices was mailed to all licensed audiologists in the State of Maryland and sent as an electronic mail attachment to the American Speech-Language-Hearing Association and Educational Audiology Association Internet forums. Common AP protocols (25 from the Internet, 28 from audiologists in Maryland) included requiring basic audiologic testing, usi...

Few studies have addressed the long-term outcomes of early brain injury, especially after hemorrhagic stroke. This is the first study to report a case of acquired auditory processing disorder in a 10-year-old child who had a severe left hemorrhagic cerebral infarction at 13 months of age, compromising nearly all of the left temporal lobe. This case, therefore, is an excellent and rare opportuni...
