Hi folks... more interesting stuff for your edification.
<p>Much has been made of the definition of the term "resonance" on this
list, and there are some who insist on defining it strictly in the direction
of "resonant frequencies".
<p>If you refer to the following URL you may find some interesting things
and links to more interesting things.

<p>Here is a quote taken from that side I thought might interest many.
<br>
<blockquote> " DEFINITION: Resonance is the process in
which oscillations in a system are produced, maintained or enhanced by
means of a periodic transfer of energy from another oscillating system,
whose frequency is identical to that of the first system.
<p>NOTE : True resonance requires the presence of either two coupled oscillating
systems (such asa the two carts), or one oscillating system and an incoming
wave(such as the two tunning forks) with matching frequencies of vibration.
There are situations when the energy is supplied continuously, but the
oscillating system only accepts energy in periodic pulses by other processes
such as auto-excitation or positive feed-back (to be discussed later) that
mimic resonance. "</blockquote>
<p>This definition clearly allows for the use of the term "resonance" such
that a soundboard can be described as a "resonator" it would seem.
