sorry
i was trying to give ans in tabular form but it get mixed
i m just rearranging it
here is the ans_
LOUDNESS:- (1) Loudness is a measure of response of our ear to the sound.
INTENSITY :- (1) It is the energy passing per second per unit area normal to the direction of energy flow
LOUDNESS:- (2) It depends on intensity as well as sensivity of the ear. therefoe , it is not absolute but relative
INTENSITY :- (2) It does not depends on the sensivity of ear
LOUDNESS:- (3) the unit is - Decibel
INTENSITY :- the unit is - Watt / m2

loudness: it physically measures how strong sound is,moreover it is depend onintensity as wellas senstivity of ear,of sound greater amplitude,greater the sound and it measured in (db) decibel.
intensity: it is a amount of sound passing through a unit area per second,it does not depend on senstivity of ear as loudness depend ,it is measure as watt/metre(square)

Loudness is a measure of response ofour ear to sound. The unit of loudness is decibel.It depends on amplitude. If the amplitude is high, the loudness also will be high.
Sound intensity is the sound power per unit area. The sound intensity is directly proportional to the square of the amplitude of sound wave.

- Sound intensity is a property of the sound source but loudness depends on the sound source, the medium and the receiver, as well.
- Sound intensity holds a small significance in problems involving human hearing system, but loudness is a very important property to consider in such problems.
- Sound intensity is measured in Watt per square meter whereas loudness is measured in Sones.

Sound Intensity
Sound intensity is the amount of energy carried by sound per unit time through a unit area of a selected surface. In order to understand the concept of sound intensity, one must first understand the concept of sound energy.
Sound is one of the main methods of sensing in the human body. We encounter sounds every day. A sound is caused by a vibration
Loudness
Loudness is defined as “the attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud,” by the American National Standards Institute. Loudness is a measurement of the sound perceived by the human ear.

i was trying to give ans in tabular form but it get mixed?
i m just rearranging it?
here is the ans_
LOUDNESS:- ?(1) Loudness is a measure of response of our ear?to the sound.
INTENSITY :- ?(1)?It is the energy passing per second per unit area normal?to the direction of energy flow

To reduce reverberations, sound must be absorbed as it reaches the walls and the ceiling of a room. Sound absorbing materials like fibreboard, rough plastic, heavy curtains, and cushioned seats can be used to reduce reverberation.

INTENSITY - A measure of field strength or of the energy transmitted by radiation . Radiant intensity , luminous intensity . Average rate of flow of sound energy usually in watts , for one period through unit area at right angles to the specified direction .

On the other hand, intensity is the sound energy passing each second through a unit area is called as intensity of the sound.
Hope this helps!

2.loudness is measured in decibels (db).
3.it depends on sensitivity of our ears.
4.it is a subjective quantity. sound can be loud for one person, but not loud for someone else.
Intensity:1. Intensity is defined as sound power per unit area.
2.it doesn't depend on sensitivity of our area.
3.it is an object quantity. it doesn't vary person to person.
4.intensity is measured in watt per meter square(W/m^2)
