{"product_id":"beats-pixel-hoodie","title":"Beats Hoodie – TWO CLOSE NOTES PULSE | Pixelated Physics","description":"\u003cp\u003eWhy do two nearly matched notes throb? Add two tones of frequencies f₁ and f₂ and you get one tone at their average pitch, wrapped in a slowly swelling envelope. The loudness peaks once every 1\/Δf seconds, where Δf is the difference, so 440 Hz and 442 Hz beat twice a second. Musicians tune until the beats stop.
