Actually you can do a search for speed of sound calculator for you temperature to get more accuracy.

All this got my mind wondering. Speed of sound is affected by temperature. 50 degrees F (10 C) speed is 1106 feet
per second. At 70 degrees F (21.1 C) speed is 1128 feeet per second. That is almost 2% faster. So an LRL frequency of say 405 Hz would be multiplied by 0.98 gives 396.9 Hz. That might not seem like much difference but I saw two tuning forks one at 440 Hz and another at 442 Hz. They do not resonate each other. Now I might not have this correct but it says higher temperatures make quite a difference in resonate frequencies.
Now I could have this the exact opposite. Colder temperatures make for a longer wavelength so that. I admit I am confused. Guess I will sleep on it study it tomorrow.
