1) Megaphones and Musical Instrumentsà Megaphones or loudhailers, horns, musical instruments are all designed to send sound in a particular direction without spreading it in all directions. In these instruments, a tube followed by a conical opening reflects sounds successively to guide most of the sound waves from the source in the forward direction.
2) Stethoscopeà In stethoscope the sound of a patient's heartbeat is guided by along the tube of the stethoscope to the doctor's ears by multiple reflections of sound.
3) Curved ceilingsà the ceilings of a concert halls, conference halls and cinema halls are made curved so that sound after reflection reaches all the corners of the halls.
4) Sound boardsà in large halls or auditorium, large concave wooden boards are placed behind the speaker. The speaker stands at the focus of this concave reflecting surface. After reflection the sound is spread evenly towards the audience. This makes the sound readily available even at a distance.
(1) Megaphone
: Megaphone is a horn-shaped tube. The sound waves are prevented from spreading out by successive reflections and are confined to the air in the tube.
(2) Hearing aidExample: The pleasant sound produced by a guitar, piano, tuning fork etc.
Noise can be defined as an irregular succession of disturbances, which are discordant and unpleasant to the ear.
EchoThe sound heard after reflection from a rigid obstacle (such as cliff, wall) is called echo.some applications of reflection of sound waves are:
1. in the measurement of distance.
2. use of SONAR in detecting sunken ships,materials in seas.
3.detection of cracks or flaws in metals.
4.determination of frequency of A.C's.
Reflection is the return of sound waves from surfaces on which they are incident.
The reflection is vibration because sound is equal to vibration
refraction is where the soubd waves bend, reflection is when sound waves bounce off of things and change direction.
A reflected sound waves is called an echo.

An echo or reverberation.
no
Angle of Incidence is equal to Angle of Reflection.

Reflection.
For eating ;)
it is a reflection because the sound waves does not travel to another medium that is the condition of refraction
The three ways that sound waves interact are: reflection, diffraction, refraction.
