Understanding the Right dB Level for Pink Noise When Using Smaart

May 17, 2024

When configuring your sound system with Smaart, an essential aspect to consider is the appropriate decibel (dB) level for pink noise. Pink noise is used as a tool for setting up and calibrating audio systems, helping you get the best performance and ensuring a downright fantastic audio experience. So, what dB level should you use for pink noise when using Smaart?

Pink Noise Basics

First, it's crucial to understand what pink noise is. Pink noise is a type of sound with a frequency spectrum that's inversely proportional to its frequency. This means that the power per frequency band is equal – a feature that makes pink noise a great choice for testing audio equipment.

Choosing the Right dB Level

When using Smaart, the ideal dB level for pink noise is determined by the specific needs of your system and environment. There's no fixed rule on the exact level to use, but here are some general guidelines to follow:

  1. Start Low: Initiate pink noise There's no fixed rule on the exact level to use, but here are some general guidelines to follow: Start Low: Initiate pink noise at a lower level, around 60-70 dB, to avoid damaging your speakers or uncomfortable sound pressure levels for people in the room.

  2. Slowly Increase: Gradually raise the volume while observing how your system reacts to the pink noise, from the microphones to speaker output. This will allow you to determine if there are any issues or room resonances that need addressing.

  3. Find the Sweet Spot: The optimal dB level for pink noise should be loud enough to provide accurate measurement data yet not too loud that it masks natural room acoustics. This typically falls between 80-95 dB, depending on your setup and environment.

  1. System Sensitivity: Consider the sensitivity of your system, microphones, and speakers. For instance, loudspeakers with high sensitivity may require a lower pink noise level to avoid overloading.


While the ideal dB level of pink noise may vary, it is essential to follow these guidelines to ensure you create the perfect audio environment using Smaart. Start low, slowly increase the level while observing your system’s response, and find the sweet spot that provides accurate measurements without compromising the room's natural acoustics.
