Why Use White Noise and Pink Noise to Test Speakers?

In acoustic testing, and pink noise are both commonly used as test signals. However, when we look at their spectral distribution, we can see that their energy is distributed in different ways.

Why Use White Noise and Pink Noise to Test Speakers?

White noise and pink noise contain different frequency components and can be used to simulate the complex sound signals that speakers may encounter in real applications. Through noise testing, we can evaluate a speaker’s durability, rated noise power, and reliability when handling instantaneous peaks.

Why Do Tweeters Often Use Spherical or Dome-Shaped Diaphragms?

Why are tweeters often designed with spherical or dome-shaped diaphragms? This is not just for appearance. It is closely related to voice coil placement, heat dissipation, high-frequency efficiency, and sound radiation. However, dome-shaped diaphragms may also introduce issues such as reflection, standing waves, and off-axis attenuation. This article explains the basic acoustic principles and design trade-offs behind dome tweeters in a simple way.
