# Noise Reduction

Minimize noise, group alerts intelligently, and auto-pause transient notifications

Not every alert should be an incident. PagerDuty's noise reduction capabilities — part of [PagerDuty AIOps](/ai-automation/aiops/overview) — leverage data science and machine learning to limit system noise and reduce alert fatigue. This means fewer incidents and interruptions for on-call responders, richer context around the incidents that do trigger, and lower resolution times.

You can access the Noise Reduction homepage in the PagerDuty web app by navigating to **AIOps**  →  **Noise Reduction**. Here you can see an overview of noise reduction features:

- [Alert Grouping](#alert-grouping)
- [Auto-Pause Incident Notifications](#auto-pause-incident-notifications)

You can create or edit settings from this central page.

> **AIOps / Signal Intelligence Feature:** This feature is included with the [PagerDuty AIOps](/ai-automation/aiops/overview) add-on, or included as Signal Intelligence in PD Reliability Platform plans. To sign up for a trial of PagerDuty AIOps features, read [PagerDuty AIOps Trials](/ai-automation/aiops/overview#pagerduty-aiops-trials).

## Alert Grouping

[Alert Grouping](/ai-automation/aiops/noise-reduction/alert-grouping) groups alerts into an incident on a service using different grouping techniques. [Global Alert Grouping](/ai-automation/aiops/noise-reduction/alert-grouping/global-alert-grouping) expands the scope of alert grouping by applying a setting across multiple services.

## Auto-Pause Incident Notifications

[Auto-Pause Incident Notifications](/ai-automation/aiops/noise-reduction/auto-pause-incident-notifications) automatically pauses notifications for transient alerts — alerts that typically auto-resolve on their own — giving them time to resolve before interrupting responders.
