棕噪音听起来怎样
Brown noise is broadband sound shaped toward lower frequencies, giving it a deep, steady rumble with much less high-frequency hiss than white noise.
That heavier balance can make traffic, ventilation, or other low background sounds feel less abrupt for some listeners. Keep it at the lowest comfortable volume that suits the room.
比较棕噪音、白噪音与绿噪音
White noise is brighter, Brown Noise is deeper, and Green Noise is shaped more toward the middle frequencies. None is universally best for sleep or focus.
Try each at a similar low volume and keep the sound that stays in the background without feeling sharp, muddy, or distracting.
