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

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 ...

Active Control mitigating the Ear Canal Occlusion Effect caused by Hearing Aids

Thomas Stefan Zurbrügg

The World Health Organization (WHO) estimates the prevalence of a disabling hearing loss to be above 5% world-wide 1. A treatment with a hearing aid - be it behind-the-ear (BTE), in-the-ear (ITE) or receiver-in-canal (RIC) - involves some degree of occlusi ...

High-field functional MRI (7 Tesla) mapping of Tonotopy in Human primary auditory cortex in patients with unilateral hearing loss and tinnitus.

Melissa Saenz, Wietske Van der Zwaag, Naghmeh Ghazaleh

Tinnitus, the chronic perception of ringing or other phantom sounds, is typically associated with hearing loss. Recent studies in mouse models have alleviated tinnitus symptom by reversing plastic reorganization observed in the tonotopic maps of primary au ...

Low Loss MEMS-Reconfigurable 1-Bit Reflectarray Cell With Dual-Linear Polarization

Julien Perruisseau-Carrier, Tomislav Debogovic

We present a X-band 1-bit reconfigurable reflectarray (RRA) cell capable of independent reflection phase control of each linear component of a dual-polarized wave. It presents the lowest loss ever reported in an operational RRA cell at microwave frequencie ...

A compact and low loss Y-junction for submicron silicon waveguide

Yi Zhang, Christophe Marcel Georges Galland

We designed a compact, low-loss and wavelength insensitive Y-junction for submicron silicon waveguide using finite difference time-domain (FDTD) simulation and particle swarm optimization (PSO), and fabricated the device in a 248 nm complementary metal-oxi ...

A High-Efficiency Nonuniform Grating Coupler Realized With 248-nm Optical Lithography

Christophe Marcel Georges Galland, Yang Liu

We describe a high-efficiency grating coupler (GC) fabricated on a silicon-on-insulator wafer with 220 nm top silicon layer. One single 60 nm shallow etch is required to define the diffractive gratings with a minimum lithographic feature size of 180 nm, wh ...

A CMOS-Compatible, Low-Loss, and Low-Crosstalk Silicon Waveguide Crossing

Yi Zhang, Christophe Marcel Georges Galland

We demonstrated a waveguide crossing for submicron silicon waveguides with average insertion loss of 0.18±0.03 dB and crosstalk of -41±2 dB, uniform across an 8-inch wafer. The device was fabricated in a CMOS-compatible process using 248 nm lithography, wi ...

Applications of dry photoresist film for printed and flexible electronics

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero

This work presents three applications of dry photoresist film for printed and flexible electronics devices. First, as part of the flexible encapsulation of printed gas sensors (i.e. humidity). This process was performed at relatively low temperatures (85 ° ...
