mtemur yes it definitely does change. it’s all related with sound velocity. if humidity, density or pressure increases sound velocity in air increases too. sound is lazy. sound waves tend to move to where sound velocity is lower. there is no way to come to a conclusion with one variable like altitude because humidity has a greater impact on sound velocity. if humidity is the same on both places than higher altitude cause more absorption than lower altitude on high frequencies. and it’s perceived as slight decrease in treble and attack. same happens if humidity decreases. >>>>>Very low humidity produces static electric charges that we know influence the sound, too. So it’s more complicated, there are many variables, some independent some dependent. As I posted yesterday velocity of sound in air probably isn’t relevant as long as the frequencies propagate at the same velocity. The ear doesn’t care how long the sound waves took to get there. Take headphones, there is almost no distance for the sound waves to travel. It takes no time for the sound to get to the ear. No time, no distance....No velocity! 🤗 |
