压迫听觉神经的肿瘤会导致潜伏期增加，这可以通过电反应测听法（BERA）从头皮上检测到。通过比较两耳的朱厄特波V或P5潜伏期，可以最好地看出反应延迟。这种耳间潜伏期差异通常小于0.2毫秒，但35例听肿瘤病例和10例其他颞骨肿瘤中的7例为0.4毫秒或更大。听觉肿瘤的大小可以从潜伏期延迟的量来估计。
Tumors that press on the audiotry nerve can cause a latency increase that is detectable from the scalp by electric response audiometry (BERA). The response delay is best seen by comparing the Jewett wave V, or P5, latencies for the two ears. This interaural latency difference is normally less than 0.2 msec, but was 0.4 msec or greater for 35 acoustic tumor cases and for seven of ten other temporal bone tumors. Acoustic tumor size can be estimated from the amount of latency delay.
