The possibility arises that high drain hearing aids may not be adequately catered for by zinc-air cells, leading to poor performance. This study investigated the hearing aid user's ability to perceive differences between zinc-air and mercury cells in normal everyday usage. The data was collected for 100 experienced hearing aid users in field trials. Users report 50 per cent greater life for zinc-air cells in high power aids and 28 per cent in low power aids. The average life of the zinc-air cells range from 15 days in high power to 34 days in low power aids. Users are able to perceive a difference in sound quality in favour of zinc-air cells for low and medium power aids. The hearing aid population is not disadvantaged by phasing out mercury cells.<\/jats:p>","DOI":"10.1017\/s002221510013871x","type":"journal-article","created":{"date-parts":[[2007,11,30]],"date-time":"2007-11-30T10:13:16Z","timestamp":1196417596000},"page":"814-819","source":"Crossref","is-referenced-by-count":10,"title":["A study of mercuric oxide and zinc-air battery life in hearing aids"],"prefix":"10.1017","volume":"111","author":[{"given":"Clive","family":"Sparkes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neville K.","family":"Lacey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,6,29]]},"reference":[{"key":"S002221510013871X_ref004","unstructured":"National Health Service supplies.
