When you see unknown plugins like ESN Sonar or a process named sonarhost.exe in your Task Manager, you might wonder if it’s safe to remove them. But before you uninstall ESN Sonar or the ESN Sonar API, it’s good to learn what ESN Sonar is.

What is ESN Sonar?

ESN Sonar is a secure file that’s made to connect to the internet. It adds a Windows Firewall exception so users can connect without any problems. Taking it away will only impact the performance of the apps linked to it. However, if ESN Sonar and sonarhost.exe cause errors and show you error messages often, you can fix them by reinstalling the app.

If you find a program or app that seems strange, the smartest thing to do is to use Anti-Virus software. It can check your program files, web pages, control panel, and storage to show you which files to delete and apps to remove. This is especially helpful if it involves cloud services, online gaming, social platforms, browsing websites, and more.

For ESN Sonar API, don’t delete it unless you know what it does first.

What is ESN Sonar and What Does it Do?

ESN Sonar is software created by a company named ESN Social Software AB. Its purpose is to connect to the internet, making a Windows Firewall exception, and allowing users to connect without any issues.

If you didn’t add the ESN Sonar API yourself or through a software installer, it likely came with one of your apps or games, such as the online game Battlefield 3 or 4 by Electronic Arts Inc. Since it works as an exception to Windows Firewall, its main job is to help players in the game chat room communicate without problems, using sonar integration as the main tool.

For players to talk effectively, the voice chat quality must be great. Adding voice communication to a game can be hard without special programs like the ESN Sonar API. That’s why it’s a key part of the game for the best performance.

ESN Sonar uses VoIP technology to send voice data through voice chat channels. When you install the Battlefield Online Game, it’s automatically added as a plugin for Google Chrome and Firefox.

Should I Take Away ESN Sonar?

If you don’t often use or need Battlefield’s voice chat option, you might be able to remove the ESN Sonar plugin. Deleting it won’t change the game’s features, and it’s simple to remove.

All you need to do is visit the programs and features area in the control panel, which is the usual method for deleting programs on Windows XP, 8, 10, 11, and so on.

However, sometimes ESN Sonar can cause problems if it isn’t installed or uninstalled the right way, or if related parts are missing or damaged.
