This study examined the effects of vocational training noise on subjective battery life and on battery current drain, in 5 different class B hearing aids worn by students at a school for the deaf. Each S used a mercury battery in the morning in an average listening school environment with a 2-hr period of vocational noise exposure included, and another battery in an average school listening environment from after lunch to bed time. Voltage measurements and usage hrs were recorded until S reported the battery was not working. There were no mean differences in subjective battery life nor in recorded voltage drop between the two conditions. Battery life in 2 batteries exposed to vocational noise may have been extended due to a 10-day rest period during the spring break for these 2 students.
本研究考察了职业训练噪音对一所聋校学生佩戴的5种不同的B类助听器的主观电池续航时间和电池电流消耗的影响。每位受试者上午在平均听力的学校环境中使用一枚汞电池，其中包括2小时的职业噪音暴露时段，午餐后至就寝时间在平均听力的学校环境中使用另一枚电池。记录电压测量值和使用时长，直到受试者报告电池无法使用。两种情况下，主观电池续航时间和记录的电压降均无显著差异。对于这两名学生，由于春假期间有10天的休息时间，暴露于职业噪音环境中的两枚电池的续航时间可能有所延长。
