For example, blue indicolite tourmaline is the only blue gemstone of any kind that will show a drag response when a neodymium magnet is applied. Any blue tourmaline that is diamagnetic can be identified as paraiba tourmaline colored by copper in contrast to magnetic blue tourmaline colored by iron.
Treatment depends on the specific cause if known as well as the extent, type, and configuration of the hearing loss. Most hearing loss results from age and noise, is progressive, and irreversible. There are currently no approved or recommended treatments to restore hearing; it is commonly managed through using hearing aids. A few specific types ...
Charoite (/ tʃ æ r oʊ. aɪ t / CHAR-ow-ait) is a rare silicate mineral with the chemical composition K(Ca,Na) 2 Si 4 O 10 (OH,F)•H 2 O, first described in 1978.It is named after the Chara River, despite its being 70 kilometres (43 mi) away from the discovery place.
Hearing loss completely recovers in around 35–39% of patients with SSNHL, usually within one to two weeks from onset. [34] Steroid treatment within seven days, a lower initial severity of hearing loss, the absence of vertigo, younger patient age, and a history of cardiovascular disease are all associated with complete hearing recovery.

Orange frames mark the region of the auditory cortex, which is displayed in the top sub-figures. Top and Bottom: Blue colors mark regions affiliated with the ADS, and red colors mark regions affiliated with the AVS (dark red and blue regions mark the primary auditory fields).
Although the envelope/fine-structure dichotomy has been debated and questions remain as to how temporal fine structure cues are actually encoded in the auditory system, these studies have led to a range of applications in various fields including speech and audio processing, clinical audiology and rehabilitation of sensorineural hearing loss ...
