Objective: To estimate the hearing aid coverage for people with disabling hearing loss using data on hearing aid sales.
Design: Data on prevalence of disabling hearing loss from WHO and on hearing loss from moderate to severe from the Global Burden of Disease enterprise are used to estimate the number of people with hearing loss. Data on hearing aid sales from the European Hearing Instrument Manufacturers Association (EHIMA) are used to estimate the number of people using hearing aids.
Study Sample: From 2009 to 2018, the worldwide sales of hearing aids by the EHIMA members were 124 million units.
Results: The world-wide hearing aid coverage is 10-11% depending on the prevalence of data source. For all low- to middle-income regions that make up 85% of the world population, the coverage ranges from 1.5% to 12%. In the group of high-income countries as defined by WHO, the coverage is 57%.
Conclusions: Data on hearing aid sales can be used to estimate hearing aid coverage regionally, and world-wide. Globally, there is a huge unmet need for hearing instruments since less than 11% of people with a disabling hearing loss are hearing aid users.

In this study, a method for determining the optimal location and orientation of an implantable piezoelectric accelerometer on the short process of the incus is presented. The accelerometer is intended to be used as a replacement for an external microphone to enable totally implantable auditory prostheses. The optimal orientation of the sensor and the best attachment point are determined based on two criteria-maximum pressure sensitivity sum and minimum loudness level sum.

Biofilm formation on cochlear implants (CIs) poses a major problem for surgeons, leading to a high incidence of explantation and revision surgery. Therefore, developing appropriate and cost-effective biofilm detection and prevention techniques is of the essence. In this systematic review, we sought to investigate the development of biofilm formation on CIs.

: Spontaneous nystagmus during vertigo attacks of Menière's disease has been essentially described as horizontal, beating ipsilaterally (irritative type) or contralaterally (deficit type) to the hearing loss. Our main objective was to describe the characteristics of nystagmus during vertigo attacks. The second objective was to determine the feasibility of self-video recording of eye movements by a mobile phone.

Attention is one of many human cognitive functions that are essential in everyday life. Given our limited processing capacity, attention helps us focus only on what matters. Focusing attention on one speaker in an environment with many speakers is a critical ability of the human auditory system.
