Hearing the noise of the trim wheels doesn't tell you if you have trimmed the aircraft.  I have used a PFC Yoke and a Saitek yoke and had to rely on pressure.  Small movements of the yoke will tell you if you are trimmed correctly or not.  I you feel resistance then you are not trimmed, if you don't feel the resistance, then you are in trim.  It's a combination of using the AI and trim switch to set your attitude. That's the way pilots do it, not by sound.

You completely missed my point. I didn't say that I am judging whether the aircraft is in trim or not by sound, of course I am doing that the way you described it (or "pilots do it"). I stated that the sound helps me in a way to get the amount of trim input roughly right the first time without having to correct it 10 times.

 

Fact is though that the delay in the trim sound is odd regardless of how i trim the plane ! 

The delay in the sound is odd, agreed, and somewhat annoying. However i still stand by if you need to hear the sound to help with trimming the aircraft properly, you aren't doing it right. I could quite easily mute the computer and trim correctly.

 

In the sim as you don't have force feedback you just make small adjustments then let some pressure off the controls and if the aircraft stays in the same attitude, it's trimmed. If the nose rises or falls against where you had it with pressure on the stick, reapply the pressure and continue trimming then gently ease the pressure off again and see if it holds the nose attitude.

 

I don't even think about it now when i do it, it's ever so small of a movement to ease off the pressure and test.

It's all about flying by feel and not on automation.  Once you get the hang of it it's easy and only requires maybe 2-3 adjustments to get the aircraft in trim.  The sound of the trim turning doesn't tell you if you have the correct trim.  If you know there is a sound delay then adjust for that delay by holding the trim switch say for 1 or 2 seconds.  Having the correct takeoff trim helps as well as you don't have to make any major trim adjustments.

No trim sound at all would be better than the delayed trim sound. It's the delay which is offputting, like hearing your own voice echo back with a delay on a phone line as you speak.
