About This Tool
This studio acoustics utility provides comparative evaluation for directional microphone proximity effects and off-axis angle factors. Enter source distance parameter 1, polar angle factor 2, and reference attenuation divisor 3.
Note on implementation: this interactive tool evaluates a proportional index ratio (val1 × val2 / val3), a geometric attenuation factor sqrt(val1 × val2), and an off-axis ratio percentage (val1 / (val1 + val2) × 100). It serves as a comparative three-variable numerical model rather than a continuous polar capsule acoustic polar graph simulator. All calculations run strictly inside your browser.
How to Use
- 1
Enter the source distance or microphone placement distance into the Value 1 field.
- 2
Enter the off-axis angle or directional pattern factor into the Value 2 field.
- 3
Set the reference attenuation threshold into the Value 3 field.
- 4
Review the calculated proportional acoustic index, root attenuation factor, and off-axis distribution percentage.
Frequently Asked Questions
Does this tool plot 2D cardioid polar graphs?
No. The tool evaluates a three-parameter proportional ratio index model for comparative placement analysis rather than generating polar response polar plots.
What causes the proximity effect in directional microphones?
In pressure-gradient directional capsules (cardioid, figure-8), low-frequency sound waves create exaggerated phase differences when the sound source is placed very close to the diaphragm, boosting bass frequencies.
Are any audio measurements transmitted to a server?
No. The entire calculation runs locally in client-side JavaScript with zero network requests.
