If someone is describing sound in first person narrative, there are instances where italics might include dashes.
How much wind pressure can a window take?
A basic residential window may have a design pressure of 15 pounds per square feet. That means, under most conditions, the window can be expected to withstand up to 15 pounds of pressure for every square foot of its surface before it breaks.
What are the three characteristics of sound?
The basic properties of sound are: pitch, loudness and tone.

Can 70 mph winds break windows?
So with all that said, at what wind speed do windows break? A Design Pressure or DP rating measures the strength of a window. Standard residential windows have DP values between 15 and 50. A DP 15 window can reasonably be expected to sustain winds of roughly 77 mph before shattering.
What can 70 mile an hour winds do?
Sustained winds to 40 to 45 miles per hour and gusts up to 70 miles per hour could cause widespread power outages, the National Weather Service said. In addition to the gusty winds, the storms will bring hail and flash flooding.

The minimum distance in which a sound wave repeats itself is called its wavelength.
How fast does wind have to be to kill you?
A far smaller amount of air speed can kill a human, as it penetrates the skin and causes local embolisms, which can quite quikly burst, causing progressive blood loss problems.

How strong does wind have to be to knock down a person?
Knocking you down would take a wind of at least 70 mph. The terminal velocity, which is the wind speed (falling speed) where the force of the wind equals the force of gravity, for a person is about 120 mph — that would likely knock you down.
What are words that describe sounds?
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as “oink”, “meow” (or “miaow”), “roar” and “chirp”.
