Room impulse responses(RIRs) have conventionally been used to derive acoustic parameters to assess acoustics of rooms. One of these parameters is reverberation time which is taken as a crucial measure for perceptual reverberance. Although this measure is not perfect on evaluation reverberance in many situations, especially when the sound decays are not exponential. This study investigates the r...

PURPOSE We measured tinnitus loudness using a new method of psychophysical scaling with the aim of introducing a potentially useful new procedure to the literature. METHOD Fourteen adults reporting tinnitus were trained to use a standardized loudness scale, and then they used that response scale to assess loudness of nonstandard stimuli and of their tinnitus. We also measured tinnitus loudnes...

OBJECTIVE The purposes of this study are to investigate the impact of topical anesthetic alone and with concurrent laryngeal telescopic examination on acoustic characteristics of vocal fold function. Comparison with phonation in controlled conditions may imply diagnostic information from the examination. STUDY DESIGN Thirty males evaluated as having a normal voice were included in the study. ...

The study was aimed to analyze the changes in acoustic parameters based upon age and gender effects and to obtain normal voice range profile (VRP) of adult male and female of three different age range. Total no. of 90 subjects were grouped into three groups as per their age (20-30, 40-50 and 60-70 years) consisting 15 males and 15 females in each group. All participants were native Bengla speak...

OBJECTIVES To assess long term (24 months) effects of the Lee Silverman voice treatment (LSVT), a method designed to improve vocal function in patients with Parkinson's disease. METHODS Thirty three patients with idiopathic Parkinson's disease were stratified and randomly assigned to two treatment groups. One group received the LSVT, which emphasises high phonatory-respiratory effort. The oth...

OBJECTIVE To assess subject tolerance of extended use of the VocaLog™ vocal monitor (VM), a device marketed to log calibrated decibel sound pressure level. STUDY DESIGN Prospective between-subjects design including two age- and sex-matched groups: individuals with Parkinson disease (IWPD) and healthy persons. METHODS After an initial session to calibrate the device and demonstrate its use, ...

This study examined the clinical feasibility, validity, and reliability of loudness growth assessment using cross-modality matching (CMM) between line length and loudness in 16 children 4 to 12 years old with normal hearing or bilateral sensorineural hearing losses ranging from moderate to severe in degree. Eight adult listeners with normal hearing were used as a comparison group. Loudness grow...

Interpreting notated music and performing it expressively is a complex skill that requires years of practice. In the quest for understanding this phenomenon, a question that arises naturally is to what degree performance directives annotated in the score affect expressive variations of tempo and loudness. Computational models of musical expression typically focus on musical structure and do not...

The primary purpose of the present experiment was to test whether the binaural equal-loudness-ratio hypothesis (i.e., the loudness ratio between monaural and binaural tones presented at the same Sound Pressure Level, SPL, is independent of SPL) holds for hearing-impaired listeners with bilaterally symmetrical hearing losses. The outcome of this experiment provided a theoretical construct for mo...

Directional loudness is that phenomenon by which the loudness of a sound may vary according to the localization of its source. This phenomenon has been mainly observed for high-frequency sounds, for sources located in the horizontal plane. Because of the acoustic shadow of the head, the left and right ear pressures are modified depending on the source azimuth and the global loudness resulting f...
