  • M ( md ) vs M (ms)

    Given M (ms) ( and other T / S parameters )
    With driver in hand ....
    Can M (md) be calculated ?
    I would like to use the ' specified M (md) '
    method with DATS to measure Vas ...

      HornResp calculates Mmd from Sd, Fs and Cms. You don't even have to know Cms, it calculates that for you from Sd and Vas.

        Found it here :

        https://cfuttrup.com/dpc/dpc.htm

        M(md)=Mvac

        * Mair, Dd
        Mair := rho/3*power(Dd,3)
        or (when measuring),
        Mair := 8/3*rho*power(Sd/PI,1.5);
        * Mvac, Mair, Mms
        Mvac := Mms - Mair;
