I Does high humidity air transfer sound better than dry air?

AI Thread Summary
High humidity can affect sound transmission, with humid air being less dense than dry air, potentially altering sound quality. Wet road conditions increase tire noise, indicating that moisture can enhance sound propagation in certain environments. Hot air's ability to hold more moisture compared to cold air may also influence how sound travels. Additionally, temperature stratification can create a waveguide effect, allowing sound to travel further than the typical inverse square law would suggest. Overall, humidity and temperature play significant roles in sound transmission dynamics.

TL;DR Summary
Sometimes highway traffic 1/4 mile away sounds like its in our yard then other times traffic is hardly noticeable.?

2 weeks of no rain traffic is hardly noticeable. Now 5 days of none stop rain traffic sounds like its in the back yard.
Does high humidity air transfer sound better than dry air?
 
Physics news on Phys.org
Road traffic makes more tire noise when the road is wet.
Humid air is less dense than dry air at the same temperature and pressure.
Hot air can dissolve more moisture than cold air.
A horizontal stratification of temperature can duct sound in a waveguide, rather than inverse square law.

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
