Estimating the Tinnitus Spectrum: A Comparison Between At-Home and Laboratory Measurements.

Purpose: The purpose of this study was to provide proof of concept for at-home measurements of the tinnitus spectrum.

Method: Nineteen participants completed pitch similarity ratings in the laboratory and at home. All participants first completed laboratory tests (at 500-16000 Hz) and then later completed at-home tests (at 250-8000 Hz) using their own personal computers and headphones.

Evaluation of a passive wearable arm ExoNET.

Wearable ExoNETs offer a novel, wearable solution to support and facilitate upper extremity gravity compensation in healthy, unimpaired individuals. In this study, we investigated the safety and feasibility of gravity compensating ExoNETs on 10 healthy, unimpaired individuals across a series of tasks, including activities of daily living and resistance exercises. The direct muscle activity and kinematic effects of gravity compensation were compared to a sham control and no device control.

Precrop-treated soil influences wheat ( L.) root system architecture and its response to drought.

Aims: Root system architecture (RSA) plays an important role in the plant's ability to sustain yield under abiotic stresses such as drought. Preceding crops (precrops) can affect the yield of the proceeding crop, partially by affecting the RSA. This experiment aims to explore the interactions between precrop identity, crop genotype and drought at early growth stages.

The Noise Reduction Algorithm May Not Compensate for the Degradation in Output Signal-to-Noise Ratio Caused by Wide Dynamic Range Compression.

Purpose: Most modern hearing aids (HAs) employ wide dynamic range compression (WDRC) and noise reduction (NR) algorithms. It is known that the nonlinear effects of WDRC and NR cause changes to the output signal-to-noise ratio (SNR) of an HA. However, the relative contributions of WDRC and NR to the nonlinear effects are not fully understood.
