Resumé

Controlling the sound field in a room with loud-
speakers, requires information about how each loudspeaker
radiates sound to the regions of interest. This information can
be estimated by in-situ measurements of the transfer functions.
However, noise in the estimates can severely deteriorate how
well the sound field is controlled. Accurate transfer functions are
especially important for sound zones, which rely on destructive
interference between multiple loudspeakers. In the presented
study, transfer function measurements from eight 10” woofers
were repeated 30 times in a room. Pressure matching was used
to create sound zones between 20-300 Hz. The performance is
evaluated for individual and averaged transfer function measure-
ments. Additionally, the effect of Tikhonov regularization based
on the estimated noise in the transfer functions is examined.
