Geez, This is probably the most aptly named thread that has ever been on Caut. Gary writes: > And we measure loudness by *amplitude* of the sound/sine >wave. So, saying the sound is "amplified" by the soundboard seems >reasonable to me. It is perfectly reasonable. Actually,loudness is defined by the human ear's perception, ie, it is "the attribute of sound measured by the magnitude of the auditory sensation" (Webster's). In musical use, the pitch is at least an equal determinant of loudness as the amplitude. Loudness is not only correlated to sound pressure level but pitch,as well. Fred writes: >>This doesn't mean that someone who thinks that a soundboard makes a string sound louder is stupid. It does mean that someone who holds that opinion is ill-informed. << Also, from Webster's: Sound is "the sensation perceived by the sense of hearing". Amplify= " to enlarge, to increase" Every piano I have ever seen has had a soundboard that increases the sensation my ears are perceiving well beyond the sound emanating from the string. The board doens't increase the energy, but it sure increases the sound. What is the basis to say that the board doesn't amplify the sound? Seems it would require atypical definitions.
