Greets!

DMB,

Got a strange one here with 2830-110124. Records 2 thru 10 makes the LW active, but returns a run-time error when clicked on. Ditto when I add a record using them. Everything seems fine from 11 upward in a sampling.

Hi GM,

This certainly is an interesting one.

Indications are that perhaps records 2 through 10 have been corrupted in some way. If you care to send me a copy of part of your Hornresp.dat data file, I would be happy to investigate further.

Double-click on the Hornresp.dat filename in Windows Explorer to open the file in Notepad, then copy and paste the first dozen or so records into a new file and forward to me at dmcbean@bigpond.com. You are welcome to send a copy of the whole file if you prefer - I realise that it is rather large :-).

Kind regards,

David

Default Throat vent expansion

Hi David:

Just a quick one - HornResp allows the user to set the type of expansion (Conical, Exponential or Parabolic) for the various segments of the horn. Can this be extended to include the throat vent too? At the moment it looks like only Conical expansion is supported (there's no option to change it to anything else).

See attached for an example, where the vent expansion from 55 cm^2 (Apt1) to 135cm^2 (at S1) is assumed to be conical.

Hi Brian,

I will have a look when I get a chance - it may take a while though, as I am very busy at the moment. Double-clicking on the Lpt label to change the flare might be the way to go. To completely integrate the feature into all the wizards etc, would however require a considerable amount of work - I may have some difficulty in justifying it :-).

For the compound horn example you have given, the limitation can of course be overcome simply by using S1, S2 and L12 rather than Ap1 and Lpt, and adding a second segment :-).

Kind regards,

David

Silly question

I've noticed there are many folks posting max SPL and the graphs look strange to me, Is the max SPL feature showing output based on constant current drive, and if so why?
