By SoundMaxPro Staff Share Share Getting clean, consistent audio isn’t just about using a good mic—it’s about placing it at the right distance and knowing how much gain to dial in afterward.

The Mic Distance Loss Estimator lets you do that math instantly: enter your microphone’s sensitivity, set the reference and target distances, and the tool plots exactly how many decibels of signal you’ll lose in free-field conditions while recommending the pre-amp gain needed to hit a healthy recording level. Built-in presets for crowd-favourite mics—from the Shure SM7B to the Neumann U87 Ai—take the guesswork out of setup, and the interactive log-scale chart makes it easy to see how moving just a few inches can change everything. Mic Distance Loss Estimator Mic Distance Loss Estimator Current Estimates: Signal at mic: -- dB SPL Needed preamp gain: -- dB Copy Gain Copied! Reference level (dB SPL @ ref-dist) e.g. 70 dB SPL measured 0.30 m from the source Reference distance (m) Default 0.30 m (1 ft) Target distance (m): 1.00 m Slider from 0.1 m – 10 m, log scale (approximated) Mic sensitivity Select Preset Mic Manual Entry (dBV/Pa) Manual Entry (mV/Pa) Pick list (dBV/Pa or mV/Pa) or manual numeric entry Desired recorded level (dBFS) Default –18 dBFS (typical headroom point) Predicted Signal & Gain vs. Distance Gain-range indicator: Shaded bands represent typical pre-amp gain capabilities: Consumer (≤ +20 dB), Prosumer (+20 – +55 dB), High-gain specialty (> +55 dB). Important Disclaimer: This tool assumes free-field conditions (-6 dB per doubling of distance). Note that room reflections/clutter, line arrays, and directional mics can significantly alter the real-world result. Use this tool as a predictive guide, not an absolute measurement.
