Acoustic and psychoacoustic aspects of vocal vibrato
This article reviews research on vocal vibrato and related phenomena. As the vibrato corresponds to a modulation of the fundamental frequency, the primary acoustic attributes are the@equency and amplitude of this modulation as well as its waveform. The range of variation of these parameters in classical operatic singing are discussed as well as the boundaries to similar phenomena such as tremol...

متن کاملVocal tremor and vibrato in the same person: acoustic and electromyographic differences.
The goal of this case study was to measure and describe differences between vocal vibrato and essential tremor of the voice in one individual who exhibited both types of modulation. Recordings of spoken and sung vowels produced by the same individual at three effort levels were examined via analysis of acoustic and laryngeal electromyographic (LEMG) signals. Modulation rate, periodicity, and sp...

متن کاملEffects of Various Type of Bentonite (Montmorillonite) on Ascites-Related Physiologic and Metabolic Factors in Broilers
This study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. Two hundred and seven days old Arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (SSB); 3) basal diet + 1% non-processed sodi...
