When 90dB is LOUDER than 120dB
To learn more about this topic, start your googling with these keywords:
Decibels (dB): a unit used to measure changes in pressure or power.
Loudness: the intensity with which a sound is perceived.
Weighted decibels (dBA): decibels that try to take into account our sensitivity for different frequencies to better approximate loudness.
Frequency: the rate at which something occurs. In the context of sound it usually means 'sound waves per second'.
Audible: perceptible for the human ear.
High sound: a sound that has a high (fast) frequency
Low sound: a sound that has a low (slow) frequency
Resonance: When multiple things have a similar frequency they will tend to move together and amplify each other.
Echolocation: Using sound to "see". Bats use this to hunt in the dark.
Equal loudness contours: Curves that show the sensitivity of the human ear along the frequency spectrum.

Why Weather Forecasts Suck
To learn more about this topic, start your googling with these keywords:
Front: a boundary separating air masses of different characteristics, such as air density, wind, temperature, and humidity
Frontal rainfall: occurs when a warm air mass comes in contact with a colder air mass
Convectional rainfall: occurs when the sun's energy heats the surface of the Earth, causing water to evaporate to form water vapour
Nowcasting: weather forecasting limited to periods less than a few hours

From the creators of the popular science show with millions of YouTube subscribers comes the MinuteEarth podcast. Every episode of the show dives deep into a science question you might not even know you had - but once you hear the answer, you’ll want to share it with everyone you know. Our team of scientists digs into the research and breaks it down into a short, entertaining explanation jam-packed with science facts and terrible puns. We’ll tell the incredible story of how monkeys crossed the Atlantic ocean on natural rafts, and we’ll explain why it gets hotter the deeper you dig underground.
