‘Acoustic shock’

Development of hearing loss due to traditional and steady state noise in working environments has well defined medical, physical and legal implications in the present times. Organisations not complying with ‘Noise at Work Regulations 1989’ are liable for compensation if...

The art and science of acoustic ecology

Aki Pasoulas summarises the diverse forms and approaches of the relatively new and expanding area of acoustic ecology, a discipline that studies the relationship between living beings and their sonic environment. Sound Ecology emerged in the late 1960s through the...

Getting to grips with acoustic trauma

Our understanding of hearing loss caused by noise exposure to those in the armed forces is growing in interest and understanding. Research at a cellular level is essential to increase our understanding so that we can better diagnose, manage and...

Acoustic shock: definitions and clinical aspects

Acoustic shock, a previously little-known and poorly understood clinical entity, came to the public’s attention in 2019 due to a high-profile legal case of a musician at the Royal Opera House. In this fascinating article, Andrew Parker and William Parker...

Military acoustic trauma: incidence and management

This is a retrospective study on the effects of acute acoustic trauma on the hearing thresholds of 225 military personnel. The main symptom after acute acoustic trauma due to firearm use was tinnitus. The authors consider it as the main...

Centralisation of care for acoustic tumour surgeries?

Several factors are responsible for readmission after acoustic tumour removal. The authors retrospectively studied the association between hospital, patient and insurance factors with the rate of readmission following acoustic tumour removal in the United States using the Nationwide Readmission Database...

Acoustic Immittance Measures: Basic and Advanced Practice

Writing a short yet comprehensive textbook to explore the vast and developing field of acoustic immittance measures seems like a challenge. This book aims to explore the core concepts behind immittance testing and provide an update on recent developments within...

Associated findings in MRI used for detecting acoustic neuroma

Presently, gadolinium enhanced magnetic resonance imaging is the ‘gold standard’ for investigating acoustic neuroma. There are often ‘incidental’ findings that may or may not be significant. In this study of 109 scans, the authors noted an uptake of 0.9% for...

Radiological diagnosis of mastoiditis in patients screened for acoustic neuroma

Magnetic resonance imaging is the ‘gold standard’ for screening patients suspected to have acoustic neuroma. Various abnormalities are picked up through this investigation, one of which, not uncommonly reported, is mastoiditis. This requires referral to otolaryngology and further evaluation. In...

Effects of blast and acoustic trauma: assessment of hearing status on war veterans

Introduction Acoustical conditions of the military are often dangerous and there is a real risk of blast trauma and acoustic trauma [1, 2]. Levels of military noises maybe reach up to 125 dBA [3]. Weapons produce instant shock waves (10μs)...

GMI A1 Acoustic Rhinometer

Using a sound pulse technique, the A1 Acoustic Rhinometer provides a rapid and non-invasive examination of the Nasal Cavity. Numerical information including distance into the nose, and volumes between certain points in the nose, are calculated and presented, highlighting and...

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...
