Pink Noise
Listen to pink noise generated directly in your browser. Pink noise places less emphasis on high frequencies than white noise, giving it a softer and deeper sound. Press play, choose a comfortable volume, and set a sleep timer if needed. Keep the volume low, especially when listening for long periods.
Choose a timer for 15, 30, or 60 minutes. The sound begins fading out 10 seconds before the timer ends.
What is pink noise?
Pink noise is a random sound with approximately equal power in each octave. Its level decreases as the frequency rises, so lower frequencies are more prominent than they are in white noise. This balance gives pink noise a softer and less hissy character. Some listeners compare it to steady rainfall, wind, or other continuous natural sounds. Pink noise is also used as a test signal when measuring speakers and room acoustics. Accurate adjustment or calibration requires suitable measurement equipment.
Pink noise, white noise, and brown noise
White noise has more energy in the higher-frequency octaves, which gives it a brighter and hissier sound. Pink noise has equal power in each octave and generally sounds softer and more balanced. Brown noise places even more emphasis on lower frequencies, giving it a deeper and more rumbling sound. Masking effectiveness depends on the level and frequency content of both the background noise and the sound you are trying to make less noticeable. Try each noise type and choose the one you find most comfortable.
