ABSORPTION OF SOUND WAVES
Vjekoslav D. Sajfert, Nicolina Pop · 2011
The effect of sound absorption in sound pipe was examined. It turned out those two types of absorption takes place in sound pipe: irreversible and reversible ones. Absorption of irreversible type has exponential distribution and for it relatively simply can be determined resulting absorption which essentially determined the quality of sound pipe. The reversible absorption decreases intensity of sound and it means that is suitable to make instruments from the woods with minimal reversible absorption characteristics.
