Deep tones are louder, but slower.

The frequency is slower, but they all travel at the speed of sound, which is constant.

in a vacuum, yes... the speed of sound is constant....

but the small amount of CO2 in air can alter the speeds of sounds higher than ~28kHz

The human ear wouldn't detect a difference, especially over a short distance that you would hear a dog barking.

true, but this is a physics question

I don't think they go over the CO2 in the air altering the speed of sound in basic physics classes. I took three physics classes and we never went over that.

frequency changes, speed is the same.
