How to Use the Hearing Module in Mac Control Center

Tucked among Control Center's optional modules is Hearing — an ear icon that most Mac users have never enabled. Behind it: Background Sounds, macOS's built-in rain, ocean, and noise generator for masking distractions, plus a headphone level readout. No third-party white-noise app required. Here's how to surface the module and what it can do.

Add the Hearing module

1. Open System Settings → Control Center.
2. Scroll to Hearing in the module list.
3. Turn on Show in Menu Bar, Show in Control Center, or both.

An ear icon appears, and clicking it opens the Hearing panel. The module is available on macOS 13 Ventura, 14 Sonoma, and 15 Sequoia, and the same toggles remove it whenever you're done — nothing else changes.

Background Sounds: the hidden noise machine

The panel's main event is Background Sounds: flip the switch, pick a sound, and set its volume with the slider. macOS ships six — Balanced Noise, Bright Noise, Dark Noise, Ocean, Rain, and Stream — each downloaded on first use, then played from disk on a seamless loop. Dark Noise is the sleeper hit for open-plan offices: it masks chatter without the hiss of classic white noise. The sound mixes under whatever else is playing, so rain behind quiet music works fine.

The same feature with a few extra options lives in System Settings → Accessibility → Audio — including its own volume control — and behaves identically whichever door you use. Because it's a system feature rather than an app, it survives quitting every app on your Mac and costs almost nothing in CPU.

Headphone levels

With headphones connected, the Hearing panel also shows a live headphone level meter while audio plays, so you can see when listening volume creeps into territory your ears will regret. It's a glanceable nudge rather than an enforcement tool — but paired with the volume keys it's an easy habit: if the meter reads loud, tap volume down twice. For AirPods and Beats the reading reflects what's actually reaching your ears, which makes it more honest than the volume slider alone.

Getting the most from the noise machine

A few habits separate people who try Background Sounds once from people who quietly run them all day. Set the volume just below noticeable — masking works at surprisingly low levels, and a sound you can consciously hear becomes its own distraction within the hour. Match the sound to the problem: Rain and Stream mask irregular noises like doors and dishes; Dark Noise blunts the low hum of traffic or HVAC; Bright Noise cuts through higher-pitched chatter. Give each a full day before judging — masking is something you notice by its absence.

Where the built-in tool ends: there's no timer, no fade-out for sleep, and no mixing two sounds together — that's dedicated-app territory. But for the core office use case, a system-level sound that keeps playing when you quit every app, survives across restarts, and costs nothing is hard to argue with. It's the rare accessibility feature that most people who find it keep — the trick, as ever, was finding it.

Background Sounds also pair naturally with a Focus mode: silence the notifications, raise the rain, and the office disappears for an hour. If you're arranging audio for comfort more broadly, the neighboring controls in Accessibility → Audio — mono audio and left-right balance — solve the "one earbud" and "off-center speakers" problems the same quiet way.
