Design and Implementation of a Composite Hydrophone of Sound Pressure and Sound Pressure Gradient [PDF]

open access: yesMicromachines, 2021
The bionic cilium MEMS vector hydrophone has the characteristics of low power consumption, small volume, and good low-frequency response. Nevertheless, there exists the problem of left–right ambiguity in the azimuth estimation of a single hydrophone.

Data for sound pressure level prediction in lightweight constructions caused by structure-borne sound sources and their uncertainties [PDF]

open access: yesData in Brief, 2023
When predicting sound pressure levels induced by structure-borne sound sources and describing the sound propagation path through the building structure as exactly as possible, it is necessary to characterize the vibration behavior of the structure-borne ...

Characterization of sound pressure levels and sound sources in the intensive care unit: a 1 week observational study [PDF]

open access: yesFrontiers in Medicine, 2023
BackgroundExposure to elevated sound pressure levels within the intensive care unit is known to negatively affect patient and staff health. In the past, interventions to address this problem have been unsuccessful as there is no conclusive evidence on ...

Auditory chain reaction: Effects of sound pressure and particle motion on auditory structures in fishes. [PDF]

open access: yesPLoS One, 2020
Despite the diversity in fish auditory structures, it remains elusive how otolith morphology and swim bladder-inner ear (= otophysic) connections affect otolith motion and inner ear stimulation. A recent study visualized sound-induced otolith motion; but

Broadband multizone sound rendering by jointly optimizing the sound pressure and particle velocity [PDF]

open access: greenJournal of the Acoustical Society of America, 2018
In this paper, a recently proposed approach to multizone sound field synthesis, referred to as joint pressure and velocity matching (JPVM), is investigated analytically using a spherical harmonics representation of the sound field.

Research on the sound absorption characteristics of porous metal materials at high sound pressure levels

open access: yesAdvances in Mechanical Engineering, 2015
Porous metal materials are widely used in noise control with high sound pressure applications such as aircraft engine liners and combustion chambers for rocket engines due to their excellent performance of sound absorption characteristics and ...

Effects of Sound-Pressure Change on the 40 Hz Auditory Steady-State Response and Change-Related Cerebral Response [PDF]

open access: yesBrain Sciences, 2019
The auditory steady-state response (ASSR) elicited by a periodic sound stimulus is a neural oscillation recorded by magnetoencephalography (MEG), which is phase-locked to the repeated sound stimuli.

Sound pressure levels generated at risk volume steps of portable listening devices: types of smartphone and genres of music. [PDF]

open access: yesBMC Public Health, 2018
BackgroundThe present study estimated the sound pressure levels of various music genres at the volume steps that contemporary smartphones deliver, because these levels put the listener at potential risk for hearing loss.MethodsUsing six different ...

Sound-Pressure Correlates of the Aortic Ejection Sound [PDF]

open access: bronzeCirculation, 1969
The sound-pressure correlates of the aortic ejection sound (AES) were studied in six patients without aortic valve disease (group 1) and in nine patients with valvular aortic stenosis (group 2) during diagnostic left heart catheterization. Aortic root sound and pressure events were recorded by a catheter-tip micromanometer simultaneously with the ...

Sound pressure level gain in an acoustic metamaterial cavity. [PDF]

open access: yesSci Rep, 2014
The inherent attenuation of a homogeneous viscous medium limits radiation propagation, thereby restricting the use of many high-frequency acoustic devices to only short-range applications.
