The bridge’s single early echo creates a broad 2300 Hz response peak.

Evidence

The short time response to a rocking impulse along the bridge, assuming only a top plate, looks like figure 18.8. The relatively weak peak at 0.00043 s with no further echoes assures a broad maximum in the admittance at 1/0.00043 = 2300 Hz. — Eric J. Heller, Why You Hear What You Hear- An…, 1776
