This study examined the relationship between hearing device price and sound quality. A novel consumer-centric metric of sound quality ("SoundScore") was used to assess hearing devices' audio performance. Each hearing device is tested with two fittings. The "Initial Fit" is designed to approximate the most likely fitting for an individual with a mild-to-moderate sloping sensorineural hearing loss. The "Tuned Fit" includes adjusting parameters optimized to hit prescriptive fitting targets (NAL NL2) on an acoustic manikin. Each fitting is evaluated across five dimensions. Both fittings are combined using a weighted average to create a single number from 0 to 5 representative of a device's overall audio performance. Seventy-one hearing devices were tested. A strong positive correlation was found between hearing device price and SoundScore. The average SoundScore increased dramatically as the price approached USD 1000, with marginal improvements beyond this point. SoundScore was consistently poor for devices under USD 500, highly variable between USD 500-1000, and consistently good over USD 1000. There is a strong but nonlinear relationship between hearing device price and sound quality. This information can aid consumers in making informed decisions while also assisting hearing healthcare professionals in providing comprehensive guidance to their patients.
本研究考察了听力设备价格与音质之间的关系。采用一种新颖的以消费者为中心的音质衡量指标(“音质评分”)来评估听力设备的音频性能。每台听力设备都进行了两种适配测试。“初始适配”旨在大致模拟为轻度至中度斜坡型感音神经性听力损失患者最可能的适配情况。“优化适配”包括调整参数,以在声学人体模型上达到规定的适配目标(NAL NL2)。每种适配在五个维度上进行评估。两种适配通过加权平均相结合,得出一个从0到5的数字,代表设备的整体音频性能。对71台听力设备进行了测试。发现听力设备价格与音质评分之间存在很强的正相关。随着价格接近1000美元,平均音质评分急剧上升,超过这个价格后提升幅度较小。500美元以下的设备音质评分一直很差,500至1000美元之间变化很大,1000美元以上则一直很好。听力设备价格与音质之间存在很强但非线性的关系。这些信息有助于消费者做出明智的决策,同时也有助于听力保健专业人员为患者提供全面的指导。
