Middle-ear reflex activity was measured in 14 listeners in response to visual and acoustic exposure to each of seven noisy toys (such as a cap gun, party horn, cow bell, and so forth). Anticipatory middle-ear reflex (AMER) activity was a common occurrence. Normal middle-ear reflex generally occurred after the sound exposure. AMERs generally occurred in the two seconds prior to sound exposure but as early as 10 seconds before sound exposure. Loudness ratings and exposure SPLs were obtained. The presence of acoustically evoked middle-ear (ME) reflex activity and AMERs to the toys was generally unrelated to SPL or reflex threshold. Many reflex responses occurred in response to exposure SPLs below reflex threshold and with low anticipated loudness rating.
对14名受试者测量了中耳反射活动，以响应他们对7种嘈杂玩具（如玩具枪、派对喇叭、牛铃等）中的每一种进行视觉和听觉暴露。预期性中耳反射（AMER）活动很常见。正常的中耳反射通常在声音暴露后出现。AMER通常在声音暴露前两秒出现，但最早可在声音暴露前10秒出现。获得了响度评级和暴露声压级。玩具引起的听觉诱发中耳（ME）反射活动和AMER的存在通常与声压级或反射阈值无关。许多反射反应是在低于反射阈值的暴露声压级和低预期响度评级下出现的。
