Sound travels with the wind. sound is a funny thing because its not a physical thing you can touch that is made from material like a plastic bag or a kite or drone and tress but sound its not physical. Its indivisible so how can the wind grab something invisible and push it along as is its made of material. Going back to decades ago. As a kid I used to play around on a hillside in an 700ft elervated position from ground level below. I always remember watching a group of people playing a game of cricket around half mile away below in the valley. There was a light breeze coming up to the hillside from there position which carried there converstion in parts past my ear. Sound is weired because it acts like its actually made from somthing but its not physical. I can never understand how that works out.
Uh in many ways sound is a 'something' as it depends on the particles in the air or ground or whatever for those waves to travel along...very similar to how a wave in the ocean works. Air is nothing more than a combination of particles and elements, which can include water, dirt, etc.
Sound travels based on many factors, almost too many to list, but depending on air density, temperature, wind, amount of particulates (i.e. rain, dust) will all help determine how well the sound travels and even how fast it will travel. Also, the area you are standing in as it relates to the sound and the direction the sound is coming from can effect your ability to hear it.
For example, some rooms allow a person's whisper to travel to the far side of it where another can hear it as if they were standing next to the person whispering, because of the acoustics of the room. The same thing can occur if you were standing inside a rock quarry with the drone above you, the sound would echo off the walls and collect in certain areas of the quarry based on the size and distance from the walls i.e. amphitheaters and how they effect sound direction and levels
To try and explain it further is going to make this very technical, and more than I'd prefer to get in to. I'm sure some can weigh in if they prefer and have the will to dive deep on the subject. |
