Why does reason crackle

But there are also other common causes of crackling in the ears as well. Affecting more than 10 million people in the United States, temporomandibular joint and muscle disorder TMJ can create stiffness and limit the movement of the jaw. Typically, jaw pain and headaches are associated with this disorder, but experiencing a crackling sound in the ears can also occur. Impacted Earwax. A secretion designed to protect the inner ears from foreign particles, earwax typically falls out of the ear on its own.

When earwax accumulates and becomes impacted, it can cover the eardrum and cause you to experience crackling sounds in your ear. If you have hearing aids, again, checking those is the first step. Dull hearing, itchy ears, and ear infections can frequently be caused by too much earwax but how could it be responsible for tinnitus noises? Luckily, dealing with earwax is frequently pretty straightforward. Your Name required. Your Email required. Phone required. Please leave this field empty.

The resulting waveform could look something like this:. In this case, the audio signal and resulting speaker driver movement are not smooth. For a brief moment, the current is interrupted, which produces a period of no voltage. We can infer that, for a brief moment, the speaker will be told to remain at rest position and not produce any sound. The pop is not from the silence of the speaker but from how the speaker is told to get to its rest position.

In the diagram above, we see that the audio signal current interruption happens just after the peak. At this point, the audio signal drops off instantaneously. The speaker driver is, therefore, tasked with being at two physical locations at the same time. In this case, it should be pushed outward and at resting position simultaneously. This is impossible. So rather than teleporting, the driver attempts to move as fast as it can between the two locations at the current interrupt.

This results in a popping or clicking sound. What happens if the current interruptions happen very often, as is the case with faulty lead wires? As we can see, there are 4 instances where the speaker is told to be in two different locations simultaneously. Another basic audio waveform in audio synthesis is the square wave. As the name suggests, it looks something like this:. A perfect square wave would actually sound terrible played back through a speaker.

There would be an inherent crackle in the waveform due to its sharp adjustment from maximum positive to maximum negative voltage and vice versa that happens in every cycle.
