How to Remove Background Noise in Premiere Pro

A workflow taught by Adobe Certified Instructors at Adobe Video World.

Hiss, hum, air conditioning rumble, echoey rooms — background noise quietly ruins otherwise great footage. The good news is Premiere Pro can clean most of it up with a few sliders, no audio engineering degree required. This guide shows you how to remove background noise while keeping your dialogue natural and clear.

Why Background Noise Matters

Audiences are remarkably forgiving of imperfect visuals but quick to click away from bad audio. A constant hiss or hum signals ‘amateur’ even when your picture looks great, and it strains the viewer over a long video.

Removing noise is one of the highest-impact fixes you can make in post. Clean dialogue feels professional, holds attention, and lets your message land without distraction.

Tag Your Clip as Dialogue

Premiere’s cleanup tools live in the Essential Sound panel (Window > Essential Sound). Select your audio clip and assign it the Dialogue type.

Tagging matters: it unlocks the right set of repair tools designed specifically for voices. The same panel handles music and effects differently, so telling Premiere what each clip is gives you the best results.

Reduce Noise

With your clip tagged as Dialogue, open the Repair section and enable Reduce Noise. This single slider targets steady background sounds like hiss, fans, and air conditioning.

Start low and raise it gradually while listening. A little goes a long way — push it too far and the noise disappears but your voice starts to sound underwater. The goal is clean, not processed.

Tame Hum with DeHum

Electrical hum — that low buzz from lights, cables, or power — has its own tool. Enable DeHum and choose the frequency that matches your region: 50 Hz in much of the world, 60 Hz in North America.

DeHum surgically removes that specific frequency without affecting the rest of your audio, making it far cleaner than trying to dial it out with general noise reduction.

Reduce Reverb and Echo

Recorded in an empty, echoey room? The Reduce Reverb slider tightens up that hollow, distant sound by reducing the reflections bouncing off hard walls.

Like noise reduction, use it sparingly. Aggressive reverb removal can make a voice sound strange and gated. A modest amount tightens the space without introducing new artifacts.

Enhance Speech Clarity

Beyond removing problems, you can actively improve clarity. The Essential Sound panel’s EQ presets include ‘Enhance Speech,’ which lifts the frequencies that make voices intelligible.

Combined with light noise reduction, this makes dialogue sit clearly in your mix. A clear voice is easier to listen to and lets viewers follow you effortlessly, even on phone speakers.

Use Loudness to Even Things Out

Inconsistent volume is its own kind of noise — viewers reaching for the remote. Use the Loudness > Auto-Match button to normalize your dialogue to a consistent, broadcast-friendly level.

Even loudness across every clip is one of the most professional touches you can add, and it pairs perfectly with a clean, noise-free recording.

Don’t Over-Process

The single biggest mistake is overdoing it. Each repair tool, pushed too hard, introduces its own artifacts — watery textures, robotic edges, pumping. The cleanest result usually uses modest amounts of several tools rather than a heavy dose of one.

Always compare against the original by toggling the effects off and on. If your fix sounds worse than the problem, dial it back. Subtlety is the mark of good audio work.

Capture Clean Audio on Set

No plugin beats a good recording. Mic your subject close, choose a quiet room, turn off noisy appliances, and record a few seconds of ‘room tone’ so you have clean silence to work with.

When you control the shoot, prevention saves hours of repair. And when you record audio separately, you’ll first need to sync it to your video before cleaning it up.

Noise Reduction Best Practices

• Tag clips as Dialogue to unlock the right repair tools.
• Use small amounts of several tools rather than one heavy fix.
• Match DeHum to your region’s frequency (50 or 60 Hz).
• Always A/B against the original to avoid over-processing.

Common Audio Cleanup Mistakes

• Cranking noise reduction until the voice sounds underwater.
• Skipping DeHum and trying to remove hum with general reduction.
• Ignoring loudness, leaving clips jumping in volume.
• Relying on repair instead of capturing clean audio on set.

A Real Noise-Cleanup Example

Imagine an interview recorded in a room with an audible air-conditioning hum. You tag the clip as Dialogue, enable Reduce Noise and raise it gently until the hum recedes, then add DeHum at 60 Hz to kill the electrical buzz underneath. A touch of Reduce Reverb tightens the roomy sound, and an Enhance Speech EQ preset brings the voice forward.

The whole fix takes a couple of minutes with a handful of sliders, and the difference is night and day. The key is restraint at every step — small amounts of several tools, checked against the original, rather than one heavy-handed pass that leaves the voice sounding artificial.

Repair in Post vs. Recording Clean

Premiere’s tools are powerful, but they work best as a safety net, not a crutch. Noise reduction can rescue a flawed recording, yet it can never fully restore detail that was masked by noise in the first place. The cleaner your source, the more natural your final audio.

Whenever you can influence the recording, invest there first: a close mic, a quiet room, and a few seconds of room tone do more than any plugin. Then reserve the repair tools for the problems you genuinely couldn’t avoid on the day.

Handle Wind, Pops, and Clicks

Background hum isn’t the only enemy. Wind buffeting an outdoor mic, plosive pops on hard consonants, and mouth clicks all need different attention. The Essential Sound panel’s DeReverb and noise tools help, while plosives are best tamed with a gentle high-pass filter or a fade across the pop.

For persistent clicks and crackle, work in short sections and listen carefully, since these transient sounds hide between words. Catching them takes patience, but clean, click-free dialogue is exactly what makes a voice comfortable to listen to for minutes at a time.

After knocking down hiss and hum, the next repair is often removing echo and reverb from audio.

Key Takeaways

• Tag the clip as Dialogue in the Essential Sound panel.
• Use Reduce Noise, DeHum, and Reduce Reverb in small amounts.
• Enhance speech with EQ and even levels with Loudness Auto-Match.
• Avoid over-processing and capture clean audio whenever possible.

Frequently Asked Questions

How do I remove background noise in Premiere Pro?

Open the Essential Sound panel, tag the clip as Dialogue, then enable Reduce Noise in the Repair section and raise it gradually. Add DeHum for electrical buzz and Reduce Reverb for echo.

Why does my audio sound underwater after noise reduction?

You’ve pushed Reduce Noise too far. Lower it until the background is quiet but the voice still sounds natural — modest settings across several tools work better than one heavy one.

What is DeHum used for?

DeHum removes the low electrical buzz from lights and cables at a specific frequency — 50 Hz in much of the world, 60 Hz in North America — without affecting the rest of the audio.
