Forward acoustic performance of a shock-swallowing high-tip-speed fan (QF-13) [PDF]
Forward noise and overall aerodynamic performance data are presented for a high-tip-speed fan having rotor blade airfoils designed to alter the conventional leading-edge bow shocks to weak, oblique shocks which are swallowed within the interblade ...

Why do bell plates ring? [PDF]
, 2003 Bell plates are polygonal plates which, when held in the hand and struck with a beater, produce an initial transient followed by a sustained, pure tone. The presence of the sustained tone depends sensitively on the shape.

Developmental sensory experience balances cortical excitation and inhibition. [PDF]
, 2010 Early in life, neural circuits are highly susceptible to outside influences. The organization of the primary auditory cortex (A1) in particular is governed by acoustic experience during the critical period, an epoch near the beginning of postnatal ...

Acoustic performance of inlet multiple-pure-tone suppressors installed on NASA quiet engine C [PDF]
The length of multiple-pure-tone (MPT) treatment required to reasonably suppress the MPT's produced by a supersonic tip speed fan was defined. Other suppression, broadband, and blade passing frequency, which might be accomplished were also determined ...

Screening methods for age-related hearing loss in older patients with cancer: A review of the literature [PDF]
, 2018 © 2018 by the authors. As people grow older, they may experience loss in hearing sensitivity. Age-related hearing loss may negatively affect the patient's quality of life as it may lead to social isolation. In older patients with cancer, hearing loss can

Improvement in word recognition following treatment failure for sudden sensorineural hearing loss
World Journal of Otorhinolaryngology-Head and Neck Surgery, 2016 Objectives: Patients with sudden sensorineural hearing loss (SSNHL) may have word recognition scores (WRS) that correlate with pure tone average (PTA). We hypothesize that there is a subset of patients with SSNHL who have improved WRS despite stable PTA.

Flight test of a pure-tone acoustic source [PDF]
Static and flight testing of a pure-tone acoustic source were conducted in order to: (1) determine if a 4-KHz tone radiated by a source in flight and mixed with broadband aircraft flyover noise could be measured on the ground with a high degree of ...
