MUIC & ACOUTIC – TRING INTRUMENT (ORCHETRAL) CALCULATOR
Pizzicato Decay Time
A precise tool.
What is the Pizzicato Decay Time & How does it work?
In the realm of music and acoustics, the decay time of a pizzicato note is influenced by various factors, including the mass of the string. The heavier the string, the longer it takes for the vibration to decay, resulting in a richer sound.
T_d = frac{m}{k} lnleft(frac{F_0}{F_t}right)
T_d = Decay Time, m = Mass of the String, k = Spring Constant, F_0 = Initial Force, F_t = Threshold Force
The decay time is calculated using the formula above, where the natural logarithm of the ratio of initial force to threshold force is multiplied by the mass of the string divided by the spring constant. This relationship highlights how the physical properties of the string directly affect its acoustic behavior.

Frequently Asked Questions
What is pizzicato decay time?
Pizzicato decay time refers to how long a plucked string on a musical instrument takes to stop vibrating after being played.
How does the mass of the string affect decay time?
Heavier strings have longer decay times because they take more energy to bring to rest, resulting in a richer sound.
What is the formula for calculating pizzicato decay time?
The formula is T_d = (m/k) * ln(F_0/F_t), where m is mass, k is spring constant, F_0 is initial force, and F_t is threshold force.
What does the natural logarithm in the formula represent?
The natural logarithm represents the rate of decay of the string’s vibration energy over time.
How do I determine the spring constant for a string?
The spring constant can be estimated by measuring the force required to stretch the string a known distance and using Hooke’s Law.
Why is initial force (F_0) important in this calculation?
Initial force determines how much energy the string has when plucked, which affects how long it takes to decay.
What is the significance of threshold force (F_t)?
Threshold force is the minimum force required to sustain the vibration; below this, the sound stops and decay begins.
