A stethoscope for imaginary sound Interactive sound in a Health Care Environment
We discuss design strategies and system development in relation to an interactive sound installation created for the Royal Victoria Hospital in Belfast. In contrast to other initiatives involving music in health care environments, the impetus of this project does not reflect therapeutic concerns, but rather the intent of enriching hospital users’ experience through the arts. This paper examines...
متن کاملA cardiac sound characteristic waveform method for in-home heart disorder monitoring with electric stethoscope
An analytical model based on a single-DOF is proposed for extracting the characteristic waveforms (CSCW) from the cardiac sounds recorded by an electric stethoscope. Also, the diagnostic parameters [T1, T2, T11, T12], the time intervals between the crossed points of the CSCW and an adaptive threshold line (THV), were verified useful for identification of heart disorders. The easy-understanding ...
متن کاملPost-Nasal Devoicing as a Sound Change
1.1. Post-nasal voicing (T > D / N ) is well attested and phonetically well motivated, both as a synchronic process and as a sound change. Locke (1983) identifies 15 of 197 languages with synchronic post-nasal voicing (PNV).1 Voicing of stops in post-nasal position is phonetically well motivated: it is the result of a combination of nasal leak and “compression” by the velum (Hayes and Stivers 2...
متن کاملStethoscope Acoustics
IT is an anachronism that the stethoscope, introduced in 1819, remains an indispensable medical tool today although no standards have ever been set for its acoustical performance.' Neither has a standard test been established for evaluating the acoustics of the intact instrument. Furthermore, there is no information on the intimate acoustical interaction of the stethoscope with the doctors' ear...
متن کاملPerformance Evaluation of Heart Sound Cancellation in FPGA Hardware Implementation for Electronic Stethoscope
This paper presents the design and evaluation of the hardware circuit for electronic stethoscopes with heart sound cancellation capabilities using field programmable gate arrays (FPGAs). The adaptive line enhancer (ALE) was adopted as the filtering methodology to reduce heart sound attributes from the breath sounds obtained via the electronic stethoscope pickup. FPGAs were utilized to implement...
