I must say about the 432 and 440 hertz controversies...I dont know if there is
only a pragmatic industry decision behind it, or not, but for sure our body react to frequencies in a direct way our consciousness did not...Then just comparing in non controlled condition few seconds songs to sense if there is a difference or not is preposterous...
It is not our biased conscious ability to do so or not, which is at stake here, but the way our body/mind react... The mind is not only the conscious tip of the iceberg we call ego...The mind is the body too...
Then we must listen to the two frequencies in an hour long comparison in few days repeat...
I am certain that a difference will be perceived...
I sense it but my listening is biased for sure... 😁😊

Abstract
Context: The current reference frequency for tuning musical instruments is 440 Hz. Some theorists and musicians claim that the 432 Hz tuning has better effects on the human body, but there are no scientific studies that support this hypothesis.
Objective: To identify differences in vital parameters and perceptions after listening to music at different frequencies, 440 Hz versus 432 Hz.
Design: Cross-over pilot study.
Setting: A room dedicated to listening to music, in an Italian city.
Participants: 33 volunteers, not suffering from acute and/or chronic diseases.
Interventions: Two sessions of music listening on different days. Both sessions used the same music (movie soundtracks) but tuned to 440 Hz on one day and 432 Hz on the other. Each session consisted of 20 min’ listening.
Main outcome measures: Vital parameters (blood pressure, heart rate, respiratory rate, oxygen saturation), perceptions (physical and emotional sensations, for example fatigue and stress), levels of concentration during the listening session, and general satisfaction with the experience.
Results: 432 Hz tuned music was associated with a slight decrease of mean (systolic and diastolic) blood pressure values (although not significant), a marked decrease in the mean of heart rate (-4.79 bpm, p = 0.05) and a slight decrease of the mean respiratory rate values (1 r.a., p = 0.06), compared to 440 Hz. The subjects were more focused about listening to music and more generally satisfied after the sessions in which they listened to 432 Hz tuned music.
Conclusions: The data suggests that 432 Hz tuned music can decrease heart rate more than 440 Hz tuned music. The study results suggest repeating the experiment with a larger sample pool and introducing randomized controlled trials covering more clinical parameters.
But this matter being very complex...
There exist also opposite conclusion from other experiment:

Conclusion: this problem is a bit more complex than meet the eye at first here...
I am not enough competent to solve it in an objective way...I hadmy opinion based only in my listening, but it will take me months of study to solve this for sure.... Not 2 articles...
😁😊
But there is another one here in favor of 432 hertz:

I disagree with your reply, and offer you... The real push behind it was nefarious, though that is denied by those who had the power to make it so.
