How To Interpret Harmonic Distortion Of Wireless Audio system

Are you seeking to get a pair of wireless audio system? You is perhaps confused by the entire technical jargon utilized by the producers to explain the efficiency of their merchandise. I’ll make clear one generally used time period which, nonetheless, is usually misunderstood: “whole harmonic distortion” or “THD”.

Wireless audio system are available in all totally different sizes and shapes. Deciding on the precise mannequin can typically be difficult. I’m going to shed some gentle on a generally used time period which is used to explain the technical efficiency of the speaker: “whole harmonic distortion” or “THD”. Whole harmonic distortion is normally not very nicely understood. Nevertheless, this phrases remains to be vital by way of figuring out the standard of a specific mannequin. Different phrases, equivalent to “output energy” or “frequency response” areĀ  normally simpler understood. Omnidirectional Condenser Mic for iPhone Android B016C4ZG74

In a nutshell, THD reveals the distinction between the sound that’s produced by the speaker versus the audio sign with which the speaker is pushed. The most typical methods to precise distortion are p.c and decibel. These two conventions might be translated into each other. The share proven as THD describes which quantity of power that’s radiated by the speaker are larger harmonics versus the unique sign. 10% would imply that one tenth is distortion. 1% would imply one hundreth and many others. 10% equals -20 dB whereas 1% equals -40 dB.

A wireless speaker really has a number of parts which contribute to harmonic distortion. One among these is the built-in energy amplifier. This amplifier is driving the speaker aspect. Normally the upper the amplifier is pushed the upper the quantity of amplifier distortion. For that reason, some producers will listing amplifier distortion relying on amplifier energy.

Harmonic distortion measurements are normally made by feeding a check tone into the speaker. This tone is a pure sine wave sign with minimal distortion. The frequency of this check tone is normally 1 kHz. Distortion, nonetheless, is normally depending on the sign frequency. Most amplifiers will present rising distortion with rising frequency. Specifically digital class-D amplifiers could have pretty excessive distortion at frequencies above 5 kHz
