individuals with Parkinson’s disease are unable to distinguish the differences in frequency, no matter what oscillation is used.

I was researching binaural beats and came across this statement.....anyone else aware of this?

That is a great article. Thanks!

This is the section you are referring to:

"It was discovered that the human brain can distinguish a differentiation of 30hz or higher as coming from two different sound sources.

That meant a binaural beats program could be effective only if the variation between the two sounds being heard is 30hz or less.

This technology was immediately implemented as a diagnostic tool because individuals with Parkinson’s disease are unable to distinguish the differences in frequency, no matter what oscillation is used."

I think that may be worded poorly. PwP can distinguish frequencies (just play a few keys on a piano). What I read (one time, somewhere) was that healthy people hear the difference between the 2 frequencies as the 3rd frequency, their brains create the 3rd frequency, but PwP do not hear the 3rd frequency.

That part about the difference in frequencies not being greater than 30 hz is interesting. I need to look into that, as I have been creating 38 hz and 40 hz gamma files.

I saw somewhere that Wikipedia had a story that PwP could not hear BB, but I just checked Wikipedia and they removed the PwP part: en.wikipedia.org/wiki/Beat_...

I am going to keep digging into this.

I absolutely love a particular binaural beats video on YouTube. It’s very calming to my 41 year old parky mind. (I was diagnosed at 30 btw) I’ll try to link to it now: youtu.be/GXeAOtb1VeAEnjoy(Not working as expected?)!!!

The link isn’t working but I’m so curious! I’m 46 ❤️

See if you can repost your favorite?

Never heard of that, before! Interesting! Thanks for sharing!

How do they know people with PD are unable to distinguish different frequencies? How can they know/test what a person hears? Does the person report what they hear? Does a person hum back the notes they can hear? I’ve just played one of the binaural beats sound tracks on YouTube and I can pick out various pitches which are happening at once. Does this mean I don’t have PD or am I misunderstanding what we’re not able to do?!

Many years ago i was a hearing aid audiologist. We would establish the patients threshold of hearing by presenting individual frequencies/decibels to each ear. They would press a button each time they heard a frequency. We established the faintest frequency and volume and would plot a graph. Maybe they went about testing in a similar fashion ? Just guessing

[Bolt_Upright in reply to JustJeff]

I took one of those hearing tests for joining the military the night after going to a rock concert. They put me in a booth and told me to press the button when I heard the tone and I kept hearing high pitched tones and pushing the button and then they came in and told me to stop playing with the button, they had not started yet.

So the whole test I had to try and differentiate the real tones from the ones in my ringing ears.

Interesting and a real problem for people with tinnitus.....one theory of tinnitus is the tiny hair cells in the cochlear cant turn themselves off and carry on ringing like a tuning fork very distressing for some people

Talking about sounds and noises. Don’t you find unbearable some kind of noises? I.e. the noise of the washing machine or the lawn mower? Or being in a room where there are several simultaneous conversations? I never read of this as a PD symptom.

[JustJeff in reply to fcerruti]

What you've described is a typical complaint from people with high frequency hearing loss. The lawnmower/washing machine background chatter are mainly low frequency and they create what's known as the upward spread of masking whereby consonants are masked and missed in speech and this coupled with a high frequency loss whereby typically a person will mistake the words being said

[Stillstandingstill in reply to JustJeff]

Interesting. I'm not sure I have hearing loss although maybe I should get it checked. My problem is that nowadays I find music too distracting if I'm doing something else. My husband likes to play it while we are eating even though it gives me indigestion. Maybe I'm just odd (poor hubby😀) But I think it's a sensory filtering problem. I hate loud noise generally. I actually love music.
