To obtain identical laboratory measures of 8 (surgical and nonsurgical) bone conduction devices and relate them to clinical function.
Each device was measured with a single laboratory system and characterized with descriptive statistics.
Laboratory.
Seven surgical devices (Intenso, BP110, BP100, and Cordelle [Cochlear, Denver, Colorado]; Ponto Pro and Ponto Pro Power [Oticon Medical, Somerset, New Jersey]; and Alpha 2 [Sophono, Inc, Boulder, Colorado]) and 1 nonsurgical dental device (SoundBite; Sonitus Medical, Inc, San Mateo, California) constituted the independent variables. Measured maximum output and gain parameters were the dependent variables.
Maximum output varied across devices in the pure-tone average (PTA; 500-3000 Hz) frequency range (mean, 109.7 dB re 1 µN; range, 98.8-119.2 dB) and in the above-PTA (4000-8000 Hz) frequency range (mean, 102.6 dB re 1 µN; range, 88.99-119.6 dB). Maximum gain varied in the PTA frequency range (mean, 40 dB; range, 29.1-49.1 dB) and was higher in the frequency range above the PTA (mean, 32.0 dB; range, 20.8-46.0 dB).
All devices have sufficient maximum output and gain for the PTA frequency range for single-sided deafness (SSD). The devices differed in maximum output and gain for the frequency range above the PTA, a consideration for accommodating presbycusis and optimizing auditory function for SSD. The surgical devices have less maximum output and gain in the above-PTA range than in the PTA range. The nonsurgical dental device had the highest output (up to 30 dB higher) and gain (up to 26 dB higher) in the above-PTA range.
获得 8 种（手术和非手术）骨导设备的相同实验室测量值，并将其与临床功能相关联。
每个设备均使用单个实验室系统进行测量，并使用描述性统计进行特征描述。
实验室。
7 种手术设备（Intenso、BP110、BP100 和 Cordelle [Cochlear，丹佛，科罗拉多州]；Ponto Pro 和 Ponto Pro Power [Oticon Medical，萨默塞特，新泽西州]；以及 Alpha 2 [Sophono，Inc，博尔德，科罗拉多州]）和 1 种非手术牙科设备（SoundBite；Sonitus Medical，Inc，圣马特奥，加利福尼亚州）构成了自变量。测量的最大输出和增益参数是因变量。
在纯音平均（PTA；500-3000 Hz）频率范围内，不同设备的最大输出存在差异（平均值为 109.7 dB 相对于 1 µN；范围为 98.8-119.2 dB），在高于 PTA（4000-8000 Hz）频率范围内也是如此（平均值为 102.6 dB 相对于 1 µN；范围为 88.99-119.6 dB）。在 PTA 频率范围内，最大增益存在差异（平均值为 40 dB；范围为 29.1-49.1 dB），在高于 PTA 的频率范围内更高（平均值为 32.0 dB；范围为 20.8-46.0 dB）。
所有设备在单耳聋（SSD）的 PTA 频率范围内都具有足够的最大输出和增益。在高于 PTA 的频率范围内，设备在最大输出和增益方面存在差异，这是适应老年性聋和优化 SSD 听觉功能的一个考虑因素。手术设备在高于 PTA 的频率范围内的最大输出和增益低于 PTA 频率范围内。非手术牙科设备在高于 PTA 的频率范围内具有最高的输出（高达 30 dB 更高）和增益（高达 26 dB 更高）。
