The requirement to phase out mercuric oxide (mercury) batteries on environmental grounds has led to the widespread introduction of zinc-air technology. 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.
基于环境原因淘汰氧化汞(汞)电池的要求促使锌空气技术得到广泛应用。有可能锌空气电池无法充分满足高耗电量助听器的需求,从而导致性能不佳。本研究调查了助听器用户在日常正常使用中感知锌空气电池和汞电池之间差异的能力。在现场试验中收集了100名有经验的助听器用户的数据。用户报告称,高功率助听器中锌空气电池的使用寿命比汞电池长50%,低功率助听器中长28%。锌空气电池的平均使用寿命在高功率助听器中为15天,在低功率助听器中为34天。对于中低功率助听器,用户能够感知到音质更有利于锌空气电池。淘汰汞电池不会使助听器用户处于不利地位。
