The Intermodulation Lockin Analyzer [PDF]
Rev. Sci. Instrum. 82, 026109 (2011), 2010 Nonlinear systems can be probed by driving them with two or more pure tones while measuring the intermodulation products of the drive tones in the response. We describe a digital lock-in analyzer which is designed explicitly for this purpose. The analyzer is implemented on a field-programmable gate array, providing speed in analysis, real-time feedback

Auditory Evoked Potential Detection During Pure-Tone Audiometry [PDF]
2021 10th International IEEE/EMBS Conference on Neural Engineering (NER), 2021 Modern audiometry is largely a behavioural task, with the pure-tone audiogram (PTA) being the gold standard for evaluating frequency-specific hearing thresholds in adults. The nature of behavioural audiometry makes estimating accurate hearing thresholds difficult in infants and people with disabilities, where following instructions or interacting with ...

Modeling Perceptual Loudness of Piano Tone: Theory and Applications [PDF]
arXiv, 2022 The relationship between perceptual loudness and physical attributes of sound is an important subject in both computer music and psychoacoustics. Early studies of "equal-loudness contour" can trace back to the 1920s and the measured loudness with respect to intensity and frequency has been revised many times since then.

COMPUTERIZED DATABASE SYSTEM FOR PURE TONE AUDIOMETRY
Nippon Jibiinkoka Gakkai Kaiho, 1993 The management and storage of pure tone audiometry data creates a major problem for otolaryngological clinics. We have devised a new computerized database system to overcome this problem. The hardware involved includes multiple audiometers and computers interfaced with a glassfiber local area network (Pi-Net).

Does dyslipidemia worsen the hearing level in diabetics?
Journal of Otology, 2017 Objective: To identify the effect of dyslipidemia on auditory function detected by Pure Tone Audiometry. To check if dyslipidemia worsens the hearing level in diabetics.

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 ...

Journal of the Acoustical Society of America, 2022 Pure-tone thresholds have long served as a gold standard for evaluating hearing sensitivity and documenting hearing changes related to medical treatments, toxic or otherwise hazardous exposures, ear disease, genetic disorders involving the ear, and ...
