Midterms - Module 4

Question 1

Is any undesirable or unwanted sound.

Answer 1

Noise

Question 2

Moments with the Highest Noise Pollution

Answer 2

1. Take-off
2. Taxiing
3. Landing
4. Low Altitudes
5. Sonic Boom

Question 3

Sources of Noise in Aviation

Answer 3

1. Noise from Engine
2. Noise from APU
3. Noise from Airframe
4. Noise from Sonic Boom

Question 4

Effects of Noise to Physiological and Behavioral Health of a Person

Answer 4

1. Speech Interference
2. Sleep Interference
3. Community Annoyance
4. Noise-induced Hearing Loss

Question 5

With the high level of noise, conversations are being drowned out or masked speech. This makes a conversation difficult to occur due to the difficulty in understanding the words being said to each other.

Answer 5

Speech Interference

Question 6

Communities near the airport are prone to sleep interference due to the loud noises originating from the aircraft which may cause interruptions to their rest.

Answer 6

Sleep Interference

Question 7

As a community, people tend to have a sentiment regarding their concerns as a group. This results in a united approach to demanding a desirable living environment.

Answer 7

Community Annoyance

Question 8

Prolonged exposure to high levels of noise can make a person deaf or can make their noise threshold shift. The lowest level of a sound the person can hear is also known as the threshold. Exposure to high noise levels can result in temporary threshold shifts or even permanent hearing impairment or loss.

Answer 8

Noise-induced Hearing Loss

Question 9

Finding Solutions for Noise Pollution from Aviation

Answer 9

1. Noise Barriers
2. Sound Insulation

Question 10

One method used at airports to battle the constant problem of noise. They are EU- adapted and meet the highest sound classes pursuant to the requirements posted by the EU. They have a completely sealed construction which allows a considerable reduction in the noise passing the barrier.

Answer 10

Noise Barriers

Question 11

Sound insulation of structures, such as residences, seeks to improve the environment indoors through treatment of the structure itself. FAA funding criteria for sound insulation projects seek a 5-dB transmission loss improvement and a day-night average sound level (DNL) goal of 45 dB indoors.

Answer 11

Sound Insulation

Question 12

Are identified in a number of forms. The highest form of regulations are those set forth in various parts of Title 14 of the Code of Federal Regulations (14 CFR). This section of the federal code is called the Federal Aviation Regulations (FAR).

Answer 12

Noise Regulations

Question 13

Sets noise standards that aircraft must meet to obtain type and airworthiness certificates for operation in the United States.

Answer 13

FAR Part 36

Question 14

Limits civil aircraft operations in the United States based on FAR Part 36 certification status.

Answer 14

FAR Part 91

Question 15

The Aviation Safety and Noise Abatement Act of 1979 (Public Law 96-193) required the FAA to establish regulations that set forth national standards for identifying airport noise and land-use incompatibilities and develop programs to eliminate them.

Answer 15

FAR Part 150

Question 16

The second major element of the national noise policy enacted through the Airport Noise and Capacity Act of 1990

Answer 16

FAR Part 161

Question 17

Describes the airport layout and operation, aircraft-related noise exposure, land uses in the airport environs, and the resulting noise-related land-use compatibility situation. It addresses the year of submission and five years into the future. It includes graphic depiction of existing and future noise exposure resulting from aircraft operations, and of land uses in the airport environs.

Answer 17

Noise Exposure Map (NEM)

Question 18

Following the development of an NEM, which essentially defines the extent of noise and land-use incompatibility, the airport proprietor may elect to develop a Noise Compatibility Program (NCP). In developing a noise compatibility program, the airport proprietor must consider all potential compatibility measures, including the airport layout, operational and use alternatives, and land use alternatives. The ultimately developed program is essentially a list of the actions the airport proprietor proposes to undertake to minimize existing and future noise and land-use incompatibilities.

Answer 18

Noise Compatibility Program (NCP)
