Development and Calibration of a New Automated Method to Measure Air Conduction Auditory Thresholds Using an Active Earplug
A new automated method termed as 'New Early Warning Test (NEWT)' has been designed to provide automatic auditory threshold monitoring in individuals exposed to high noise levels. The NEWT method is incorporated inside an active communication earplug called Quietpro®, which has high attenuation...
Spectral analysis of internally leaking shut-down valves
We herein describe the results obtained from a set of experiments conducted on a shut-down valve, the objective of which was to identify the degree of internal leakage through the valve in its closed state. Leakage in a valve is not only a concern in terms of safety, but can also contribute to high...
A Comparison Study of Foam versus Custom Silicone Earplugs Used as Part of an Intelligent Electronic Hearing Protector System
Detection and quantification of valve through leak from the analysis of acoustic emission (AE)
Based on literature studies of acoustic emissions (AE) from leaking valves the basic behaviour of such emissions is described. Some important factors affecting the scaling of the emissions are discussed briefly. Oppdragsgiver: Project 3.2 within Center for Integrated Operations in the Petroleum...
