# 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](https://support.pagerduty.com/main/docs/aiops) — 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** :fa-arrow-right: **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.
### Availability
This feature is available with the [PagerDuty AIOps](https://support.pagerduty.com/main/docs/aiops) add-on. If you would like to sign up for a trial of PagerDuty AIOps features, read [PagerDuty AIOps Trials](https://support.pagerduty.com/main/docs/aiops#pagerduty-aiops-trials).
# Alert Grouping
[Alert Grouping](https://support.pagerduty.com/main/docs/alert-grouping) groups alerts into an incident on a service using different grouping techniques. [Global Alert Grouping](https://support.pagerduty.com/main/docs/global-alert-grouping) expands the scope of alert grouping by applying a setting across multiple services.
# Auto-Pause Incident Notifications
[Auto-Pause Incident Notifications](https://support.pagerduty.com/main/docs/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.
