Tinnitus Sound Therapy Trial Shows Effectiveness for Those with Tinnitus.

Background: It is well accepted among clinicians that maskers and hearing aids combined with counseling are generally helpful to tinnitus patients, but there are few controlled studies exploring the efficacy of maskers alone to decrease the prominence of tinnitus.

Purpose: We investigated the benefit of maskers for patients with chronic, bothersome tinnitus.

Research Design: Crossover single-participant design, where each participant served as their own control.

Tinnitus Suppression in Cochlear Implant Patients Using a Sound Therapy App.

Purpose: The use of acoustic stimuli to reduce the prominence of tinnitus has been used for decades. Counseling and tinnitus sound therapy options are not currently widespread for cochlear implant (CI) users. The goal of this study was to determine whether tinnitus therapy sounds created for individuals with acoustic hearing may also benefit CI users.

Investigating social discrimination of group members by laying hens.

Social relationships in domestic fowl are commonly assumed to rely on social recognition and its pre-requisite, discrimination of group-mates. If this is true, then the unnatural physical and social environments in which commercial laying hens are typically housed, when compared with those in which their progenitor species evolved, may compromise social function with consequent implications for welfare. Our aims were to determine whether adult hens can discriminate between unique pairs of familiar conspecifics, and to establish the most appropriate method for assessing this social discrimination.
