WINC: A Wireless IoT Network for Multi-Noise Source Cancellation

Haitham Al Hassanieh, Jiaming Wang, Junfeng Guan

This paper introduces Wireless IoT-based Noise Cancellation (WINC) which defines a framework for leveraging a wireless network of IoT microphones to enhance active noise cancellation in noise-canceling headphones. The IoT microphones forward ambient noise ...

Daily Contributors of Tinnitus Loudness and Distress: An Ecological Momentary Assessment Study

Patrick Karl Alois Neff

BackgroundTinnitus is a heterogeneous condition which may be associated with moderate to severe disability, but the reasons why only a subset of individuals is burdened by the condition are not fully clear. Ecological momentary assessment (EMA) allows a be ...

Wave-conversion active liner based on generalized Snell-Descartes law

Hervé Lissek

The Cremer’s impedance theoretical framework has been used for years to optimally design acousticliners for the aeronautic industry, such as honeycomb liners. This passive mean of sound absorption,which consists in rather thin (a few centimeters) honeycomb ...

Duct modes damping through an adjustable electroacoustic liner under grazing incidence

Hervé Lissek, Romain Boulandet, Gaël Matten

This paper deals with active sound attenuation in lined ducts with flow and its application to duct modes damping in aircraft engine nacelles. It presents an active lining concept based on an arrangement of electroacoustic absorbers flush mounted in the du ...

Surgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal

Demetri Psaltis, Simon Nessim Henein

Objective: To enable development of an endoscope for cellular-level optical imaging of the inner ear. Study Design: A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range o ...

Hearing assistance system

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

There is provided a hearing assistance system, comprising a transmission unit (10) comprising a microphone arrangement (17) for capturing audio signals from a voice of a speaker ( 11 ) using the transmission unit and being adapted to transmit the audio sig ...

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Emmanuel André Henri Bossy

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 mu m inner diameter and 30 mm long). An optical-resolution photoacoustic image of a 30 mu m diameter absorbing nylon threa ...

Investigations on the physical factors influencing the ear canal occlusion effect caused by hearing aids

Hervé Lissek, Thomas Stefan Zurbrügg

The occlusion effect refers to the altered perception of one's own voice when the ear canal is fully or partially obstructed. While the loudness increase due to body conducted sounds requires an assessment by psychoacoustic methods, the ratio of sound pres ...

Phase noise measurement of external cavity diode lasers and implications for optomechanical sideband cooling of GHz mechanical modes

Tobias Kippenberg, Albert Schliesser

Cavity-optomechanical cooling via radiation pressure dynamical backaction enables ground-state cooling of mechanical oscillators, provided the laser exhibits sufficiently low phase noise. In this paper, we investigate and measure the excess phase noise of ...

A UAV Motor Denoising Technique to Improve Localization of Surrounding Noisy Aircrafts: Proof of Concept for Anti-Collision Systems

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

Unmanned Aerial Vehicles (UAVs) have become very affordable and small in recent years, and are increasingly used in a wide range of monitoring and surveillance applications. A major problem when operating with swarm of UAVs is the risk of mid-air collision ...
