Shane M wrote Air density varies inversely proportional to temperature? Sound (vibration) will travel slower through denser materials.
That's my guess. It's been a few years. ************* No so. If you heat up the air in your horn, the density decreases. But if you compress some air while keeping it at room temperature, the speed of sound will stay the same. It's not true that sound always travels slower in denser materials. The speed of sound in water is greater than the speed of sound in air, even though the density of water is much greater. A second factor which contributes to the speed of sound through a material is the compressibility. The smaller the compressibility, the greater the speed of the wave. Although the density of water is greater than the density of air, its compressibility is MUCH less than the compressibility of air. Compressibility is different from comprehensibility. Comprehensibility depends on how dense a listener is. If you have trouble understanding the difference, please ask someone else to explain it to you.
