What is the suggested masking level to eliminate crossover responses?

The suggested masking level to eliminate crossover responses is indeed 60 dB pe SPL (pressure equivalent sound pressure level). This level is established based on the principle that adequate masking is necessary to prevent auditory stimuli presented to one ear from being perceived by the other ear, which can lead to misleading results in auditory testing.

Employing a masking level of 60 dB pe SPL is considered effective because it is high enough to ensure that the signal intended for one ear is sufficiently masked from being detected by the contralateral ear, thus helping to confirm the integrity of the test results. The choice of using pressure equivalent sound pressure level is important in this context, as it aligns with the standards for auditory thresholds and ensures that the masking effect is optimized.

In contrast, the other suggested levels may not provide the same degree of masking efficacy, as they are either lower than recommended or do not align with the standard practices in intraoperative monitoring and auditory testing settings. Employing insufficient masking levels could result in incomplete or inaccurate interpretations of the auditory stimuli, potentially leading to misdiagnosis or complications during procedures.
