Frequency Compression – is there a benefit?

The goal of this study was to investigate whether frequency compression (FC) hearing aids provide more benefit than conventional hearing aids. Twelve experienced hearing aid users 65-84 years of age with moderate to severe high frequency hearing loss wore the...

Is auditory frequency discrimination related to speech recognition in implantees?

Why do two identical implantees perform differently? This fundamental question has not yet been answered despite the extensive research in the field. The authors attempted to clarify the issue, or at least approach it, assessing the association between deficits in...

High Frequency Ear Simulator

With GRAS’ new Ear Simulator, it is now possible to measure up to 20 kHz with precision, consistency and good repeatability. The new ear simulator complies with IEC 60318-4 and is well suited as a supplement to the standardized ear...

Which cross-over frequency is best for electro-acoustic stimulation?

Advances in technology and improved soft surgical techniques have led to individuals with better hearing thresholds, especially at the low frequencies, becoming candidates for cochlear implants (CI). Surgeons are more confident that residual hearing can be preserved thus making those...

The effects of hormonal changes across menstrual cycle on high frequency auditory thresholds

Physiological changes during the menstrual cycle are well documented; do these changes extend to the auditory system? Lalsa Shilpa Perepa and Rewa Indurkar delve into the literature to find the evidence. Menstrual cycle refers to a series of changes that...

Unravelling the Meniere’s vs. migraine conundrum – what does the mastoid contribute?

This is an interesting observational study that attempts to classify subtypes of Meniere’s disease (MD) in relation to the coexistence of migraine. It is well known that the two conditions share common characteristics, making diagnosis and treatment challenging at times....

Making sense of modern wireless hearing aid technologies

Before diving into the topic of the technology behind wireless hearing aids, it is important to define two key concepts. The first is wireless frequency. This is the frequency at which a wireless signal is transmitted. In the context of...

Hearing loss in the contralateral ear after mastoid drilling

It is difficult to conceive that most of the noise generated by drilling the mastoid would not be conveyed to the contralateral cochlea, by direct transmission through the skull bone, where the attenuation factor is only 5-10 dB. Only a...

Post-operative debridement following FESS

Postoperative treatment pathways for patients following functional endoscopic sinus surgery (FESS) vary widely with the topic of debridement of the nasal cavity a subject of conjecture. This article is the result of two independent reviewers using the consort guidance for...

Clinical strategies for improving music listening

For audiologists and patients alike, the technical challenges of fitting hearing aids for music are well known. Drs Greasley and Crook introduce their research and top tips for improving satisfaction in this important topic. Hearing aids are often problematic for...

Effect of COVID-19 on hearing and balance

Rhinological symptoms are cardinal features of COVID-19. However there have only been anecdotal reports on the involvement of the ear, the closest neighbour to the nose and throat. The aim of this study was ‘to assess the presence of persistent...

Rotational chair testing: “To rotate, or not to rotate, that is the real question”

Passive whole body rotation tests are widely considered to be the ‘gold standard’ for the identification of bilateral peripheral vestibular disorders (bPVD), but also have a part to play in identifying unilateral disorders (uPVD). In this article Paul Radomskij discusses...
