Calibration of Clinical Audio Recording and Analysis Systems for Sound Intensity Measurement
American Journal of Speech-Language Pathology, 2015Purpose Sound intensity is an important acoustic feature of voice/speech signals. Yet recordings are performed with different microphone, amplifier, and computer configurations, and it is therefore crucial to calibrate sound intensity measures of clinical audio recording and analysis systems on the basis of output of a sound ...

Digital recording and computer-based analysis of lung sounds
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002The human ear is one of the most efficient instrument for detecting patterns in acoustic signals. Therefore, auscultation is an important and easy to use tool in clinical diagnostic routines. A computer-based system for recording and analysis of lung sounds cannot replace the human ear, but can complement it.

Sound analysis of temporomandibular joint internal derangements with phonographic recordings
The Journal of Prosthetic Dentistry, 2003Temporomandibular joint (TMJ) sound recordings could be analyzed to assess the state of TMJ internal derangements.The aim of the study was to assess the value of sound analysis in the diagnosis of the type of the TMJ internal derangements.After clinical and radiologic examinations, phonographic sound recordings on mandibular excursions were obtained in

We present a multi-feature approach to the detection of cough and adventitious respiratory sounds. After the removal of near-silent segments, a vector of event boundaries is obtained and a proposed set of 126 features is extracted for each event. Evaluation was performed on a data set comprised of internal audio recordings from 18 patients.

Detection of explosive cough events in audio recordings by internal sound analysis
2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017We present a new method for the discrimination of explosive cough events, which is based on a combination of spectral content descriptors and pitch-related features. After the removal of near-silent segments, a vector of event boundaries is obtained and a proposed set of 9 features is extracted for each event.

Performance analysis of seismocardiography for heart sound signal recording in noisy scenarios
Journal of Medical Engineering & Technology, 2016This paper presents a system based on Seismocardiography (SCG) to monitor the heart sound signal for the long-term. It uses an accelerometer, which is of small size and low weight and, thus, convenient to wear. Such a system should also be robust to various noises which occur in real life scenarios.

An accurate recording system and its use in breath sounds spectral analysis
Journal of Applied Physiology, 1983An accurate recording system was set up and used for analyzing normal and asthmatic breath-sound features. Breath sounds are recorded at the trachea simultaneously with the airflow signal at 0.5- and 1-1/s levels. The study was carried out in the frequency domain using a fast-fourier transform (FFT).

Directional Recording and Analysis of Sounds from Musical Instruments
The Journal of the Acoustical Society of America, 2008The sound of musical instruments doesn't radiate omni directionally into the sound field. Moreover, each component of the sound (e.g. a partial) can have its own directivity pattern which, in turn, may also vary over time. In general, the radiated sound in free space will have a different timbre at different locations around the sound source.
