The physical phenomenon termed “the compression of standing waves” or “standing wave compression” was first discovered in geometric models in 1981. With this discovery, Russian physicist Yuri N. Ivanov conducted a geometric analysis of wave phenomena in relation to the Albert Michelson experiment which explained Michelson’s null results and mathematically justified the newly discovered physical phenomenon. It was not until 1990 that an acoustic experiment was conducted to confirm the existence of this physical phenomenon.

During the experiment, the compression of standing waves was not only found to occur along the longitudinal orientation of the device to the motion of the medium, but at any orientation. In other words, the experiment fully confirmed the theoretical predictions.

In 1990, the aforementioned series of experiments using sound to create standing waves was carried out. In these experiments, it was reliably established that with an increase in the wind speed relative to the two stationary sound emitters, a package of standing sound waves is compressed.

In windless weather (experiments usually began in the calm before a thunderstorm) a standing sound wave was created between the first emitter and the second emitter. With the help of a sound indicator (microphone) the node of the standing wave was found. When the wind appeared, the shift of the control node in the direction of the second emitter was recorded. This observed effect was interpreted as the compression of a package of standing sound waves.

This experiment:

  • confirmed that when the speed of the system in the medium changes or the speed of the medium changes relative to the system, standing waves in the system begin to compress. That is, a new physical phenomenon called “standing waves compression” appears.
  • showed that standing wave compression really exists in nature and that this phenomenon can even manifest itself at the level of electromagnetic waves. Therefore, it is likely that this phenomenon can explain the negative results of Albert Michelson’s experiments.
