# Creating a Coverage Beam
Create Coverage Beam
A Coverage Beam is a customizable, highly directional beam of sound powered by HOLOPLOT’s Optimization Engine. Coverage Beams create an optimal listening experience for audiences in areas of any shape.
Coverage Beams create custom directivity patterns by targeting zones as areas to cover or avoid. You can specify the spectral and temporal properties of the beam and consider custom room temperature and humidity factors. The key difference between Coverage Beams and Parametric Beams and Virtual Sources is that Coverage Beams undergo a cloud-based optimization process that is calculated based on the zones and parameters added by you. Therefore, you should have a stable internet connection anytime you want to optimize a Coverage Beam.
You can create and optimize up to five Coverage Beams per array. To add a Coverage Beam to your Array, you must first add an Array using the **Create Array** option in the toolbar. Next, click **Create Coverage Beam** in the contextual menu. Once a Coverage Beam is created, you will see the Properties Panel appear on the right, where you can add parameters specific to that beam.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.holoplot.com/holoplot-plan/working-with-beams/creating-a-coverage-beam.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
