71 Hz Pure Sine Wave

71 Hz phase-locked mono sine wave that runs for 10 hours. Best suited for: • Experiments • Subwoofer testing and loudspeaker burn-in. • Finding room modes and acoustic resonances in your studio or home cinema. • Low-end audio calibration and technical frequency tests. BUILD YOUR OWN WOBBLE BASS (INTERACTIVE SOUND LAB): You can use this channel as a modular synthesizer grid. Don't just listen to one frequency – create your own heavy acoustic beats and morphing wobble basses right inside your room: 1. Open this video in a browser tab. 2. Open a second video from our channel (e.g., with a 1 Hz or 4 Hz difference) in a second tab. 3. Start both videos simultaneously. Depending on the distance between the two frequencies, you will create a faster or slower physical wobble effect (schwebung). The interaction happens directly in the air of your room or through your speakers. Perfect for sound design inspiration, subwoofer testing, and acoustic experiments! 💡 IMPORTANT AUDIO NOTE: To accurately feel these sub-bass frequencies, a dedicated subwoofer or high-quality studio headphones are required. Most standard smartphone or laptop speakers cannot physically reproduce sounds below 50 Hz.
