The Audible Nature Of Knock

[InterCooL]

hey guys

how easy is it to hear knock?

as in, can a dyno tuner with the headphones on, can he hear knock at low levels better than the knock sensor?

or does the PFC interpretation of the knock sensor show a more sensitive and accurate reading?

would you want to tune to the knock sensors number output, or a good set of ears?

an autospeed article claims that ears pick up on knock before electronic devices. but everyone on this forum backs their knock sensors as if they give a gold perfect reading.

edit: yes i'm talking about the ability to hear with headphones, not just hanging your head out the window whilst driving

All I can say is - if you can hear knock, then it's too late.

If a human ear picks it up better than an electronic ear, why on earth do manufacturers bother fitting knock sensors?

I think the difference is if your plugged into the mic with ur ears you will pick it up easier.

Knock sensors use a algorythm to analyse the knock and only report it depending on amount of knock, well at least thats how I was told the stock system works.

after market options are alot better, as are aftermarket mics. Audiable knock when outside the vehicle means some serious knock is happening and yes then its too late, damage had prob occoured.
