PLZ HELP ME ASAP IT DUE TODAY Research and write a short paper (1-2 pages) on the field of sound engineering or acoustic architecture. Be sure to include the kind of training that people need to practice in this field and the kinds of job opportunities that are available. You might want to look into anechoic chambers and write more about how they are made and what they are used for.

The “Wheel of Acoustics” was created by R. Bruce Lindsay for The Science of Acoustics, published in the Journal of the Acoustical Society of America. This wheel shows the fields of acoustics starting with the four broad fields of Earth Sciences, Engineering, Life Sciences, and the Arts.

The outer circle lists the various broad disciplines one may study to prepare for a career in acoustics.

The inner circle lists the fields within acoustics to which many fields naturally lead.

You can find more information about 8 different fields of acoustics below and read about different careers in acoustics on the Meet Acousticians page.

General Acoustics

Fields of Acoustics- General

Material in this category covers the science of sound and waves. How sound is created, how it travels and how it is received. How materials react to different types of sounds is also important in this field.

This field includes Engineering Acoustics, Physical Acoustics, and Signal Processing in acoustics, and others.

Animal Bioacoustics

Fields of Acoustics - Animal Bioacousstics

Animal Bioacousticians study how animals make, use and hear sounds. Animal bioacoustics also includes the use of sound to study and detect the presence of animals and their behavior, the sounds they make, the effects of man-made noise on animals, and the use of SONAR to monitor the presence of plankton and fish.

This field includes Acoustical Oceanography, Animal Bioacoustics, Underwater Acoustics, and others.

Explanation:

THANK MY ANSWER AND MARK ME AS BRAINLIST

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
