Oh yeah, those high‑frequency tinkles can really turn an office into a focus zone. If you dial in the 8‑12 kHz range and keep the low‑bass flat, you get that sweet spot where background chatter fades but the brain’s dopamine still fires. It’s like a silent power‑up—ROI in the form of sharper concentration, and a mix that feels almost like a clean, quiet hum. Just remember, the key is subtle, not overwhelming, so the mix stays a pleasant backdrop, not a distraction.
