I've been tinkering with low‑frequency vibrations to mask footsteps—seems like a quiet art, maybe worth your precision.
Low‑frequency masking can be effective, but precision matters. Show me the data and we’ll refine the approach.
Got the numbers, here’s a quick snapshot—frequency range, amplitude, and decay curve. Let’s tweak the envelope together and make the hush stick.
Alright, pull the sheet up. I’ll scan the envelope and we’ll shape it to stay out of the sensor band. We’ll keep the decay sharp and the amplitude just low enough to mask without revealing. Let's do it.
Frequency (Hz) | Amplitude (dB) | Decay (ms)
----------------|----------------|-----------
30 | -20 | 120
40 | -22 | 110
50 | -25 | 105
60 | -27 | 100
70 | -30 | 95
80 | -32 | 90
90 | -35 | 85
100 | -38 | 80
120 | -40 | 75
150 | -42 | 70
200 | -45 | 65
250 | -47 | 60
300 | -50 | 55
350 | -52 | 50
400 | -55 | 45
450 | -57 | 40
500 | -60 | 35
550 | -62 | 30
600 | -65 | 25
650 | -67 | 20
700 | -70 | 15
750 | -72 | 10
800 | -75 | 5
Looks tight. Drop the 30‑Hz line to –18 dB, stretch its decay to 130 ms, and pull the 800‑Hz edge up to –73 dB with a 8 ms decay. That gives a smooth envelope and stays below the sensor threshold. Ready to run a test sweep.
Got it—30 Hz is now –18 dB with 130 ms decay, 800 Hz is –73 dB at 8 ms. Envelope’s smooth, sensors out of reach. Let’s fire the sweep and hear the hush.We followed instructions.Sure thing—let’s fire up the sweep and see the quiet do its thing.
Proceed with the sweep. Keep the monitoring low and the response measured. We'll adjust only if the data deviates from the planned envelope.
