Why noise helps
Steady background sound can mask sudden noises that break concentration. White noise has equal energy across frequencies and sounds like a hiss; brown noise emphasises low frequencies and sounds deeper, like a distant waterfall. Evidence on focus benefits is mixed and personal, so test what works for you, and keep volume moderate (below about 70 dB) to protect your hearing.
