Sonometer 3 Wire Pattern
DDAFRICA-001-0034
The Sonometer 3 Wire Pattern is a hollow wooden sounding box with three wires stretched over fixed bridges 72 cm apart and mm scales between them. One wire is tensioned through a spring balance reading to 100 N, one passes over a pulley for loading, and the third is set by a wrest-pin for comparison.
The sonometer lets three stretched wires be compared on one sounding box: one under a tension measured on the spring balance, one loaded over a pulley and one set with a wrest-pin. The three movable bridges change the vibrating length, which can be read from the mm scales between the fixed bridges. A pack of replacement steel and brass wires, each in 22, 24 and 26 SWG, is sold separately.
