Single-notch and double-notch sensorineural hearing losses were observed in 27 adult patients. All patients denied having a history of noise exposure, but did report at least one episode of hear trauma. Generally, the laterality and degree of hearing loss did not appear to correlate well with severity and site of head trauma, or post-traumatic symptoms. Although not all individuals suffering head trauma will yield notch audiograms, when an audiometric notch is observed the possibility of head trauma as well as other factors should be explored in the patient's history.
在27例成年患者中观察到单切迹和双切迹感音神经性听力损失。所有患者均否认有噪声暴露史，但均报告至少有一次听力创伤事件。一般来说，听力损失的侧别和程度似乎与头部创伤的严重程度和部位或创伤后症状没有很好的相关性。虽然并非所有头部创伤患者都会出现切迹听力图，但当观察到听力测定切迹时，应在患者病史中探究头部创伤以及其他因素的可能性。
