Walleye sit in the middle of the hearing league: no bone chain linking swim bladder to inner ear, so nothing like a carp's amplified hearing — but the otoliths still register engine rumble, hull slap, and dropped pliers just fine.

The interesting part is how differently that plays out by depth. Over open water, walleye are famously tolerant of trolling noise: boats pass overhead all day on Lake Erie and the fish keep eating, partly because in 10 m+ (33 ft+) the boat is distant, the sound field is diffuse, and fish habituate to steady, predictable engine drone the way they habituate to waves. Some trollers even argue prop wash stirs and concentrates fish; treat that claim as unproven — but steady noise clearly does not kill a deep bite.

Flip it shallow and everything reverses. A walleye hunting a 1–2 m (3–6.6 ft) rock flat at night is an alert animal in thin water with nowhere to go. There, hull slap, a banged cooler, a wading angler's crunching steps, and sudden lights will end the spot.

FAQ

Does boat noise or an ice auger spook walleye?

It depends on depth and context. Walleye hunting a calm, shallow flat at night are genuinely spooky — outboard passes, hull slap, and dropped pliers will move them, which is why night casters plan quiet drifts and long casts. Fish at 8–10 m (26–33 ft) under a working walleye chop are far more forgiving; trollers run right over them all day. On the ice, an auger absolutely announces you, but the disturbance fades within minutes — the standing advice of drilling all your holes early, then fishing quietly through the prime dusk window, exists because it works. As a rule: the shallower and calmer the water, the more silence pays.
