Relationship of Pure Tone Audiometry and Ossicular Discontinuity in Chronic Suppurative Otitis Media
Philippine Journal of Otolaryngology Head and Neck Surgery, 2006 Background: Pure tone audiometry is routinely used to determine conductive and sensorineural hearing status. Ossicular discontinuity is usually assessed intra-operatively.

Two-mode squeezed states in cavity optomechanics via engineering of a single reservoir [PDF]
Phys. Rev. A 89, 063805 (2014), 2014 We study theoretically a three-mode optomechanical system where two mechanical oscillators are independently coupled to a single cavity mode. By optimized two-tone or four-tone driving of the cavity one can prepare the mechanical oscillators in an entangled two-mode squeezed state, even if they start in a thermal state.

Effect of Pitch on the Asymmetry in Global Loudness Between Rising- and Falling-Intensity Sounds [PDF]
Acta Acustica united with Acustica, Hirzel Verlag, 2018, 104 (5),
pp.770 - 773, 2018 The global loudness of a varying intensity sound is greater when the intensity increases than when it decreases. This global loudness asymmetry was found to be larger for pure tones than for broadband noises. In this study, our aim was to determine whether this difference between pure tones and noises is due to the difference in bandwidth between ...

Effect of HIV and Antiretroviral Treatment on Auditory Functions
International Archives of Otorhinolaryngology, 2018 Introduction Numerous studies have evaluated auditory functions in human immunodeficiency virus (HIV) patients; however, these studies had a few major limitations in terms of methodology as they used mainly evoked audiometry although this method is ...

Tactile responses in pure-tone audiometry: a saccule function? [PDF]
European Archives of Oto-Rhino-Laryngology, 2013 As generally accepted, low-frequency bone-conduction thresholds obtained in the 35–55 dB range are often tactile responses and not due to auditory stimulation [4]. Since it is recently known that low-frequency airand bone-conducted stimuli can be used to test otolithic function also in humans [2], we wondered if such ‘‘false-positive’’ boneconduction ...

Pure tone audiometry with and without specific ear protectors
Brazilian Journal of Otorhinolaryngology, 2008 The authors evaluated pure tone audiometry with and without specific ear protectors.The purpose of this case control study was to measure the level of sound attenuation by earplugs.The evaluation included sixty ears of 30 subjects of both sexes, aged between 20 and 58 years, of various professional activities, with normal hearing thresholds, and ...

Auditory streaming emerges from fast excitation and slow delayed inhibition [PDF]
arXiv, 2020 In the auditory streaming paradigm alternating sequences of pure tones can be perceived as a single galloping rhythm (integration) or as two sequences with separated low and high tones (segregation). Although studied for decades, the neural mechanisms underlining this perceptual grouping of sound remains a mystery.
