i've done an exp where i have a signal generator connected to a speaker. It's then passed through a soundproof box which i made with cardboard with corrogated cboard lininig. I then have carboard barriers for the sound to pass through. The sound reaches the mic whcih is connected to a CRO. I will then calculate the attenuation
I have found that the 1st barrier makes the biggest difference, and that the attenuation just gets less and less after that. Do you agree with this, and do you have any comments about the experiment?

Many thanks

Is this some kind of optical illusion or can it be explianed by the theory of relativity

Ok...you travel back to meet yourself at age 18; you give your younger self stock market secrets and winning mega-lottery numbers as well as personal advice about bad relationships and people to avoid. Then you time travel back to the present day. Would you rememeber only your original life and the trip back in time? Or would you know everything your rich younger self experienced from age 18 to the present? For instance; if you where single-broke and lonely when you went back in time and when you returned you where rich and married to your dream lover...would you know your lover?
