Boquipequeña: Hearing & Inner Ear
① Underwater sound (1480 m/s) · ② Closed swim-bladder resonance · ③ Otolith localization · ④ Granite/cobble bottom reflects hull noise. Hard rock bounces trolling-motor pulses and 200 kHz pings like concrete; make long casts, silence transducers on shallow reefs, and tick lead across gravel.
B Rock Shoal Hull & 200 kHz Sonar Discipline vs Natural Gravel Tick — Hard rock bounces trolling-motor pulses and 200 kHz pings like concrete; make long casts, silence transducers on shallow reefs, and tick lead across gravel. match sound to water — rattles for stain, wind, and current; quiet baits for calm and clear — and run a quiet boat: low motor speeds, soft feet, long casts so the fish hears the bait before it ever hears you.

Smallmouth hear the same low rumble-and-thump band as their relatives — the difference is the water they hear it in. In the clear, quiet lakes and rivers smallmouth favor, sound carries information and alarm in equal measure, and the balance tips differently than it does for a stained-water largemouth.
Loud can repel. A heavily rattling bait that calls largemouth out of dirty water can turn clear-water smallmouth away — a very common pattern is rattles earning their keep in stained rivers, wind, and chop, while silent or one-knock baits win on calm, transparent flats. When a smallmouth can already see the lure from meters away, extra noise adds suspicion, not attraction.
Your noise counts double. Because these fish often sit in 3–9 m (10–30 ft) of clear, still water, hull slap, a dropped pliers, hatch lids, and abrupt trolling-motor bursts travel to them fast and clean. Pressured smallmouth demonstrably drift off spots under boat traffic and return when it quiets.
