less harsh sounds for anvils and glass

What I Want Done:

Anvil's sounds and Glass block Breaking sounds need to be re-engineered to be less harsh.

possibly also the iron block placement/breakage.

Why I want it done:

the sounds of anvils landing/being used/breaking/etc, the iron blocks being placed and broken, and glass breaking are extremely harsh on the ears, to the point of being painful even at moderate or low volume. much more so even than similar blocks that were added more recently, such as village bells, copper blocks, and amethyst crystals respectively.

I cannot use anvils, place iron, or break glass in the game without it being physically painful for me- I have autism, and certain frequencies are very painful to listen to; but my autism is mild so this is an issue i think might affect people without disabilities as well.

How I suggest it be done:

Re-design the glass breakage to be similar to the amethyst crystals; high frequencies should be lesser in volume, dissonant frequencies should have their phases more aligned and volume reduced as well.

I have gotten brief headaches frequently from glass and anvil sounds in Minecraft and i hope that this gets taken into serious consideration for the purpose of accessibility for those who cant listen to the audio without adverse affects.
