Re: [Fwd: Re: cross-modality-size-loud]

In addition, there are a couple of studies investigating perception of the acoustic effect of the physical size of musical instruments, animals, and humans. It also seems that there are specific regions in the human brain which are responding to the acoustic and/or crossmodal aspects of size in sounds.

Best regards,

Quoting "Hermes, D.J." <D.J.Hermes@xxxxxx>:

First, there should be no confusion between pitch and timbre.  If an
object has more than one modal frequencies, a percept of pitch only
brought about when the frequencies of the components are harmonic.  In
principle, it is possible that modal frequecies can go up on average,
but that in the new configuration a lower fundamental frequency arises.
Second, an example of counterintuitive rising of modal frequencies with
size is increasing the thickness of a plate.  Due to the higher
stiffness of thicker plates their resonance frequencies are higher.
Some informal demonstrations I gave during lecturing shows that the
human listener is indeed fooled by this and, based on their sounds when
hit, judges the thicker plates as "smaller" than the thinner plates.
Detailed studies about size and speed perception of rolling balls can be
found in the theses by Marc Houben en Christophe Stoelinga, and the
papers they published and will publish.  Loudness only plays a minor
role in this.

Is there likely to be some pitch-with-resonance component? -
ie, larger objects have longer 'intrinsic reverberation'
(body resonance) than smaller, other things being equal
(material, etc) - and this actually tends to be lower, for
larger objects regards ppl

Dear Peter,

if you hit a large bell and a small bell, how loud they are
does not depend on size, but on how hard you hit them. The
larger the object the deeper the sound, because resonant
frequency is proportional to mass. So if there is a link with
size, then it should be pitch more than loudness.

psychological data reported which refutes (or not) the

predisposes to the perception also of "has much of quality
Y"? E.g., is there empirical evidence for cross-modal bonds
like "large objects (much of size) are loud objects (much of
sound)" ? Although I see brain research approaching the
subject (e.g.  http://www.dhushara.com/pdf/synesthesia.pdf )
I have not (yet) found so much empirical psychology about
such metaphors. I may not have studied carefully enough the
synaestesia literature, but appreciate any more specific
'forwardings' then.Pieter Jan Stallen / Chair Community Noise
