Ancient Lithuanian Kanklės / Acoustics

Dynamically diapason

Dynamically diapason is the interval between the smallest and highest sound intensity. It is measuring according to the formula 20 lg( S/S_o ) = X db (intensity in decibels), where S - the biggest, S_o - the smallest deviation from the zero lone, that is dedicated as the measure unit.

Pictures: the diagrams of dynamically diapason of the kanklės of Suvalkiečiai:

1. - e¹ (320 Hz) with a bone (about 16 db);

2. - e¹ (320 Hz) with the finger (about 12 db).
