Table 3.

Individual broadband noise (BBN) and narrowband noise (NBN) thresholds.

Subject	Condition	BBN	10–20 kHz NBN	16–20 kHz NBN	15–17 kHz NBN
Green 1	Baseline	2.6 dB SPL	1.6 dB SPL	6.8 dB SPL	11.3 dB SPL
	Saline	1.2 dB SPL	2.7 dB SPL	6.7 dB SPL	7.7 dB SPL
	Salicylate	17.7 dB SPL	16.1 dB SPL	26.3 dB SPL	30.5 dB SPL
Green 3	Baseline	2.0 dB SPL	−0.5 dB SPL	12.0 dB SPL	8.1 dB SPL
	Saline	1.5 dB SPL	−0.7 dB SPL	8.1 dB SPL	6.5 dB SPL
	Salicylate	21.1 dB SPL	22.6 dB SPL	24.5 dB SPL	26.8 dB SPL
Purple 2	Baseline	4.8 dB SPL	NA	NA	NA
	Saline	7.1 dB SPL	NA	NA	NA
	Salicylate	24.7 dB SPL	NA	NA	NA
Purple 3	Baseline	1.8 dB SPL	1.0 dB SPL	9.2 dB SPL	7.7 dB SPL
	Saline	−0.1 dB SPL	−1.2 dB SPL	8.6 dB SPL	4.0 dB SPL
	Salicylate	18.3 dB SPL	19.2 dB SPL	19.8 dB SPL	21.7 dB SPL
Mean	Baseline	2.80 dB SPL	0.67 dB SPL	9.28 dB SPL	9.00 dB SPL
	Saline	2.43 dB SPL	0.27 dB SPL	7.80 dB SPL	6.07 dB SPL
	Salicylate	20.45 dB SPL	19.30 dB SPL	23.53 dB SPL	26.33 dB SPL

According to this table, a 20 dB SPL BBN following an injection of salicylate would only be 2.3 and 1.7 dB above threshold for green 1 and purple 3, respectively; the BBN would be below threshold for Purple 2 and Green 3.
