Description
Beat rate in hertz from the absolute frequency difference of two close tones.
Beats Frequency implements a focused acoustics calculation. Beat rate in hertz from the absolute frequency difference of two close tones.1
When to use Beats Frequency
Use this calculation for a first-order acoustics estimate when the stated geometry, propagation model, averaging convention, reference quantity, and SI units match the measurement or design problem.
- First Hertz
- A finite measured or assumed value greater than or equal to 0, expressed in Hz.
- Second Hertz
- A finite measured or assumed value greater than or equal to 0, expressed in Hz.
How Beats Frequency calculates the result
The implemented rule is: Beat rate in hertz from the absolute frequency difference of two close tones.
- Beat Hertz
- The calculated beat hertz, expressed in Hz.
Limitations of Beats Frequency
This is an idealized calculation rather than a complete acoustic simulation or measurement. Reflections, boundary conditions, directivity, damping, frequency dependence, near-field behavior, background noise, transducer response, temperature, humidity, and geometry can change a real result.
Alternative or Complementary measurements
Confirm important results with calibrated measurements or a model that includes the actual geometry, materials, boundaries, source directivity, and frequency-dependent losses. Preserve the reference quantity and weighting whenever a result is expressed in decibels.
