# What would happen if you increase the intensity of a sound?

## What would happen if you increase the intensity of a sound?

The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder.

What is the intensity of sound for 100 dB?

Learning Objectives

Table 1. Sound Intensity Levels and Intensities
Sound intensity level β (dB) Intensity I(W/m2) Example/effect
90 1 × 10–3 Inside a heavy truck; damage from prolonged exposure
100 1 × 10–2 Noisy factory, siren at 30 m; damage from 8 h per day exposure
110 1 × 10–1 Damage from 30 min per day exposure

### Which sound is 100 times louder than the sound with 10 decibel intensity?

30 dB sound
The decibel scale is logarithmic scale that goes up by powers of ten. Every increase in 10 decibels (dB) on the scale is equivalent to a tenfold increase in sound intensity, which roughly corresponds with loudness. So a 30 dB sound is 100 times louder than a 10 dB sound.

How many times does the intensity of sound increase when the intensity level increases by 20 dB?

A sound that is 10*10 or 100 times more intense (1*10-10 W/m2) is assigned a sound level of 20 db. A sound that is 10*10*10 or 1000 times more intense (1*10-9 W/m2) is assigned a sound level of 30 db. A sound that is 10*10*10*10 or 10000 times more intense (1*10-8 W/m2) is assigned a sound level of 40 db.

#### What determines the intensity of sound?

The closer the particles get or the further apart they get, the greater the sound’s amplitude. Sound amplitude causes a sound’s loudness and intensity. The bigger the amplitude is, the louder and more intense the sound. Sound intensity is measured in Watts per meters squared.

What is the dB measurement for a sound intensity that is 100 times more intense than 0 dB?

20 dB
Regarding the units of 10 as mentioned above, a sound 10 times greater in intensity will be measured as 10 dB; a sound 100 times more intense than 0 dB will be measured as 20 dB; a sound 1,000 times greater in intensity than near silence will be measured as 30 dB, and so on.

## Which of the following intensities is 100 times greater than 10 dB?

30 dB
The level of noise in a quiet bedroom, 30 dB, is 100 times louder than 10 dB.

What does a 10 dB increase in sound mean?

For example, every increase of 10 dB on the decibel scale is equal to a 10-fold increase in sound pressure level (SPL). Near silence is expressed as 0 dB but a sound measured at 10 dB is actually 10 times louder. If a sound is 20 dB, that’s 100 times louder than near silence.

### What happens when sound intensity is doubled?

The logarithmic sound intensity level scale match the human sense of hearing. Doubling the intensity increases the sound level with 3 dB (10 log (2)).

When the sound intensity is doubled What is the increase in the acoustic intensity level?

Answer : If the intensity of sound is doubled, 3.010 dB sound level will increase.

#### What factors affect intensity of sound?

Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.
