Energy harvesting from vibrations with a nonlinear oscillator [PDF]
, 2009 In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator.

Pure-tone sensitivity of human infants [PDF]
The Journal of the Acoustical Society of America, 1986 Pure-tone thresholds at frequencies ranging from 250 to 8000 Hz were estimated for 3-, 6-, and 12-month-old infants and for adults, using the Observer-based Psychoacoustic Procedure (OPP). Sounds were presented monaurally using an earphone. Psychometric functions of infants were similar to those of adults, although 3-month-olds had shallower functions ...

Adult hearing screening: the Cyprus Pilot Program
Audiology Research, 2011 Hearing loss is the third most common condition affecting adults over 65 (Cruickshanks et al., 1998). It can affect quality of life, limiting the ability to communicate efficiently, and leading to isolation, psychological strain, and functional decline ...

Perspectives on the Pure-Tone Audiogram [PDF]
Journal of the American Academy of Audiology, 2017 Background:The pure-tone audiogram, though fundamental to audiology, presents limitations, especially in the case of central auditory involvement. Advances in auditory neuroscience underscore the considerably larger role of the central auditory nervous system (CANS) in hearing and related disorders.

Can unilateral, progressive or sudden hearing loss be immune-mediated in origin? [PDF]
, 2017 OBJECTIVE: The aim of the present study was to demonstrate that the positivity of nonspecific immunological tests could be found not only in bilateral hearing loss but also in unilateral cases, either sudden or progressive. METHOD: An observational case

Functional magnetic resonance imaging measurements of sound-level encoding in the absence of background scanner noise [PDF]
, 2002 Effects of sound level on auditory cortical activation are seen in neuroimaging data. However, factors such as the cortical response to the intense ambient scanner noise and to the bandwidth of the acoustic stimuli will both confound precise ...

Spectral and temporal gating mechanisms enhance the clutter rejection in the echolocating bat, Rhinolophus rouxi [PDF]
, 1991 Doppler shift compensation behaviour in horseshoe bats, Rhinolophus rouxi, was used to test the interference of pure tones and narrow band noise with compensation performance.
