目前还没有研究表明哪只耳朵应该佩戴助听器。对58例双侧听力损失25- 75dB HL的患者，每耳依次配戴耳位助听器10周。然后询问患者他们对拟合侧的偏好，以及他们这种偏好的原因。35例患者具有对称听力：17例（49%）偏好一侧耳朵，因为他们在该耳使用助听器可以听得更好，12例（34%）出于实际原因选择一侧。23例患者的听力不对称：8例（35%）由于实际原因更喜欢一侧，13例（57%）在一只耳朵中使用助听器可以听到更好的声音，这总是听力较差的耳朵。由于无法可靠地预测首选耳，因此应提供双侧耳模。如果只提供一个模具，它应该是为听力较差的耳朵。
No previous study has investigated which ear should be fitted with a hearing aid. Fifty-eight patients with bilateral hearing loss of 25-75 dB HL were sequentially fitted with an ear level hearing aid for 10 weeks in each ear. Patients were then asked their preference for side of fitting, and their reasons for this preference. Thirty-five patients had symmetrical hearing: 17 (49%) preferred on ear because they could hear better with the aid in that ear, and 12 (34%) chose one side for practical reasons. Twenty-three patients had asymmetrical hearing: 8 (35%) preferred one side for practical reasons, and 13 (57%) could hear better with the aid in one ear, which was invariably the poorer hearing ear. As the preferred ear cannot be reliably predicted, bilateral ear moulds should be provided. If only one mould is provided, it should be for the poorer hearing ear.
