At low volume, your ears drop the bass

These are the Fletcher-Munson equal-loudness contours. Each curve represents the SPL needed at every frequency for your ear to perceive the same loudness. At low volume, you need dramatically more energy in the bass and treble just to hear them.

The shaded region shows the gap between what you hear at low volume (20 phon) and loud volume (80 phon). OIKLA fills that gap in real time.

How It Works

Measure

OIKLA knows how loud you're actually listening — it measures the real level at every frequency.

Correct

It boosts the frequencies your ears would otherwise miss at that volume — more bass, more treble, perfectly balanced.

Enjoy

Full, rich sound at any volume. Your ears think it's loud, but the actual level stays safe.

Built for How You Actually Hear

Real-Time Processing

Continuous loudness compensation with under 3ms latency. No buffering, no delay — you won't notice it's there.

Full-Spectrum Correction

4,096+ frequency bands individually corrected to restore the bass and treble your ears miss at low volume.

Continuous Adaptation

The correction updates in real time as your listening level changes. No manual adjustment needed.

True Stereo

Independent left/right channel processing preserves spatial imaging and stereo width.

How Human Hearing Works

Based on ISO 226 equal-loudness contours — the standard model of how your ears respond at different volumes.

Your Target Level

Set the perceived loudness you want. OIKLA compensates so it sounds full at any volume.

Without OIKLAWith OIKLA

At low volume, your ears lose sensitivity to bass and treble. The outer frequencies fade away, leaving a thin, mid-heavy sound.
