The loudest a sustained sound can possibly be on Earth's surface is
194 dB
—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).
Which sound wave is louder?
The amplitude of a sound wave determines its loudness or volume.
A larger amplitude means a louder sound
, and a smaller amplitude means a softer sound. In Figure 10.2 sound C is louder than sound B. The vibration of a source sets the amplitude of a wave.
What is the loudest sound can be?
The
Krakatoa volcanic eruption
: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away. 3. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.
What makes a sound wave louder?
Their vibrations occur in the same direction as the direction of travel. Sound waves can only travel through a solid, liquid or gas. When an object or substance vibrates, it produces sound.
The bigger the vibrations, the greater the amplitude
and the louder the sound.
Does higher pitch mean louder sound?
Children will often mix up pitch and loudness believing that
a higher pitched sound is a louder one
. Higher pitched sounds produce waves which are closer together than for lower pitched sounds. … A smaller triangle or cymbal will make a relatively higher pitch note.
How do I make my sound louder?
Smartphones can have volume limit tools to help protect your hearing. When it comes to Androids, some have it while others do not. If you're using a Galaxy or any other relevant device, you can go into your Sounds and Vibrations menu,
select the Volume option, and then adjust the Media Volume limiter
.
Why is sound a wave?
Sound is
produced when an object vibrates, creating a pressure wave
. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
What Hz is harmful?
Especially dangerous is infrasound at the
frequency of 7 Hz
, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity.
How loud can a human yell?
Human screams can be quite loud, possibly
exceeding 100 dB
(as of March 2019, the world record is 129 dB!)
How loud is 145 decibels?
| Decibel Level Source | 110-140 dB Rock concerts | 130 dB Jet takeoff, shotgun firing | 145 dB Boom cars |
|---|
What makes sound quieter or louder?
Bigger vibrations make louder sounds
, and smaller vibrations make quieter sounds.
How high or low a sound is?
A low- frequency sound is
about 500 Hz or lower
. A high- frequency sound is about 2,000 Hz and higher. Intensity is measured in decibels (dB) [DES-uh-buls]. A high-intensity (loud) sound has a high decibel level.
What makes sound loud or soft?
Volume is how loud or
soft
a sound is. The volume depends on the amount of energy in a sound wave. If you hit a table hard it will make a louder sound then if you hit is soft. A human can hear 120 decibels but it is very painful.
Is pitch and loudness the same?
Difference between Pitch and Loudness
The pitch of a sound is our ear's response to the
frequency
of sound. Whereas loudness depends on the energy of the wave. … The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
Why do high notes sound louder?
High frequencies are perceived
louder than low frequencies by the human ear
. So in order to become louder when singing deep notes, more air is required. The deeper you get, the quieter you become, the more air you need.
Why is sound high pitch?
Sounds are determined by how an
object vibrates
. Volume is dependent on how hard the air is pushed through. … Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.
