Unwanted sound can have a negative impact on patient outcomes and caregiver effectiveness. Speech privacy is crucial to protecting patient rights under HIPAA. However, recent studies show that hospital noise levels have increased significantly over the past five decades. Understanding the basics of sound transmission and measurement is essential to a realistic assessment of a facility’s sound e...

Introduction[N1] :One of these annoying stimuli and a major source of stress in the NICU is sound. In neonatal intensive care units, sounds with different intensities and frequencies are produced from different sources such as fan devices, intermittent alarms, ventilators, telephones, door opening and closing, and staff conversations; Studies have reported that the average noise level in the NI...

1/f noise or pink noise, which has been shown to be universal in nature, has also been observed in the temporal envelope of music, speech, and environmental sound. Moreover, the slope of the spectral density of the temporal envelope of music has been shown to correlate well to its pleasing, dull, or chaotic character. In this paper, the temporal structure of a number of instantaneous psychoacou...

This paper presents a partially implemented layered software architecture for describing and designing environmental sounds (everyday sounds) in non visual interfaces based on a new sound model (audio framework). This architecture facilitates non-speech audio presentation of objects and interaction mechanisms to non visual interfaces. Physical layer, system sound software layer, sound analyser/...
