    - - Type of road vehicles
        
        is created during the process of compression and expansion in the engine, creates engine vibrations then emit noise
        
        volume, speed, and capacity
      - Driving style and driver behavior
        
        hook the horn unnecessary

        designed to reduce aviation noise levels
        
        largest noise source was the compressor, turbine, and jet exhaust
        
        Newer turbofan engine models have succeeded to reduce the aforementioned noise levels
      - aircraft structure
        
        landing gear, aircraft wings, and the flaps
        
        The noise generated by these aircraft parts depends on different aircraft configurations

- - - - Blood pressure levels, cardiovascular disease, and stress-related heart problems
    - - poor for memory, making it hard to study
      - affects brain responses and people’s ability to focus, which can lead to low-performance levels over time
      - leads to lower response rates as well as making the mind dull

    - - rely on echolocation to communicate, navigate, feed, and find mates, and excess noise interferes with their ability to effectively echolocate
      - Whales and dolphins are particularly impacted by noise pollution
    - - soriented more easily and face many behavioral problems
      - animals may suffer from hearing loss, which makes them easy prey and leads to dwindling populations
