If you scroll through social media for any length of time, you’ll likely find videos claiming that listening to songs tuned to “A 432Hz” can be incredibly calming and soothing.
It is also claimed that by listening to music tuned to this frequency, you can tune your internal frequency to the frequency of the universe. It’s a fascinating idea that simply listening to music tuned in a certain way can improve your health.
But is there any scientific basis for it?
ancient ideas
First, what does it mean that a song is tuned to A 432Hz?
Hertz (or Hz) is a measurement of frequency, or the number of vibrations of a sound wave per second. Sound travels through the air as waves and hits the eardrum, producing the sensation of hearing. The faster the sound waves vibrate, the higher the pitch of the sound.
In standard concert tuning, the note A above middle C is tuned to 440Hz. 432Hz tuning simply means that the pitch of A and all other notes in the music are tuned a little lower than normal.
Some argue that 432Hz is closer to the natural harmonic frequency than 440Hz, so it is healthier to use this adjustment.
The idea that sound and music can heal us or bring us into alignment with the universe is not new. Long before social media, the ancient Greeks connected sound to cosmic frequencies. Pythagoras proposed that musical notes were governed by simple numerical ratios, which he believed supported the universe itself.
Medieval and Renaissance thinkers then built on these ideas the concept of “music of the spheres.” The idea is that sound can be used to align with the vibrations of the planet in a kind of cosmic harmony that affects human emotions and well-being.
no magical effect
Although the concept of a cosmic alignment is interesting, there is little scientific support for the idea that certain frequencies have any magical effect on happiness.
In a 2019 study, researchers played participants a movie soundtrack tuned to 440 Hz on one day, and a movie soundtrack tuned to 432 Hz on another day, and found that participants who listened to the 432 Hz tuning experienced a slight decrease in heart rate and blood pressure. However, this study was limited by a very small sample and non-randomization of participants, making it difficult to separate true frequency effects from expectancy and general relaxation responses.
New research suggests that the health effects of sound and music are less about a single special frequency and more about how we perceive and interpret sounds.
Some theorize that using frequencies that correspond to specific brain wave patterns, such as delta waves (0.5-4Hz, associated with deep sleep) and alpha waves (8-12Hz, associated with relaxed wakefulness), allows the brain to synchronize to those frequencies and achieve a relaxed state.
However, research supporting this theory is not conclusive. A 2017 study found no changes in electrical activity in the brain after hearing such frequencies presented as binaural beats.
Binaural beats themselves are another form of sound that many claim can have miraculous effects on well-being. When two slightly different frequencies are played separately to each ear, the brain perceives rhythmic pulses at a rate equal to the difference between the two frequencies. This is called binaural beat.
There is some evidence that our physiological systems (such as breathing and heart rate) are synchronized to every beat we hear. This helps reduce the level of arousal and arousal.
This is why most of us tend to gravitate towards slower, gentler sounding music when we want to relax. This is because slow beats slow down your breathing and heart rate, which can help you feel sleepier and calmer.
focus on one’s own reactions
Does this mean that binaural beats have a special therapeutic effect? not much.
A recent study found that binaural beats can increase relaxation and change brain activity. Importantly, however, similar effects were observed with other types of moving and spatialized sounds. The authors concluded that this benefit was likely driven by general auditory characteristics rather than the binaural beats themselves.
It all depends on personal preference and perception. For example, binaural beats are often associated with meditation and mantras. And it may be this association that enhances the supposed well-being effects of binaural beats for some people.
A The same goes for music tuned to 432Hz.
Our brains tend to interpret sounds as expressions of emotional states. When humans are relaxed, the pitch of our voice is usually lower than when we are excited or excited.
Therefore, sounds with a lower pitch may be perceived as more relaxing than sounds with a higher pitch. Again, this doesn’t mean there’s anything special or magical about 432Hz tuning. It’s just that for many people, lower pitched sounds are more important. seems to be Be more calm. You can get the same effect by listening to other music or lower pitched frequencies.
So while 432Hz may sound pleasing to some ears, it is not a shortcut to cosmic alignment. Instead of thinking about numbers, focus on actually being aware of your own reactions. Notice how different sounds make you feel, what slows your breathing, eases your body, and lifts your mood.
When it comes to happiness, what works for you is what works for you.
