how loud is the sun?
434824
The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun's surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

The Sun contains approximately 1057 atoms of hydrogen.

Some noise code laws also prohibit any sounds exceeding 10 decibels of the ambient sounds level from any property or public street. According to NYC Quiet Hours specified in Local Law 113, neighbors in all five boroughs are bound to quiet hours from 10 pm until 7 am.

Humans can hear frequencies of up to 20,000 Hz, dogs hear around 45,000 Hz, cats up to 64,000 Hz, and mice up to 95,000 Hz. We are most sensitive to sounds of around 3,000 Hz.

The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.

An outwardly expanding shock wave is generated, with matter reaching velocities on the order of 5,000–20,000 km/s, or roughly 3% of the speed of light. There is also a significant increase in luminosity, reaching an absolute magnitude of −19.3 (or 5 billion times brighter than the Sun), with little variation.

The apparent magnitude of the Sun is −26.74 (brighter), and the mean magnitude of the full moon is −12.74 (dimmer). The Sun appears about 400000 times brighter than the full moon.

Most bat echolocation occurs beyond the range of human hearing. Humans can hear from 20 Hz to 15-20 kHz depending on age. Bat calls can range from 9 kHz to to 200 kHz. Some bat sounds humans can hear.

In general, you are allowed to play music in your backyard at a reasonable volume from sunrise to sunset. Local authorities often have little or no basis to prevent you from playing music, even somewhat loudly. ...

You see, the range of human hearing is about 20Hz-20KHz. But that's an ideal range, covering almost all of the population. Most infants will be able to hear that full range, and a few people might be able to hear frequencies a bit higher or lower.

The Sun releases an estimated 384.6 yotta watts (3.846×1026 watts) of energy in the form of light and other forms of radiation. We are able to survive on Earth because the energy is spread over the area of a sphere with a radius of approximately 93,000,000 miles.

Sirius A is about twice as massive as the Sun ( M ☉) and has an absolute visual magnitude of +1.42. It is 25 times more luminous than the Sun but has a significantly lower luminosity than other bright stars such as Canopus or Rigel.

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.

Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. When an aircraft is near the sound barrier, an unusual cloud sometimes forms in its wake.

Louder: UE says Boom 2 is 25% louder than its predecessor thanks to some decibel tweaking. ... Long battery life: You can listen to the UE Boom 2 for 15 hours on a single charge. Super portable design: The compact, cylindrical design makes this speaker perfect for sliding in your bag and hitting the road.

Time restrictions on loud music Noise from music that can be heard in any habitable rooms of a neighbouring residence must cease during certain times: midnight to 8am on Friday, Saturday or any day preceding a public holiday and 10pm to 8am on any other day.
