What You'll Learn
Air traffic
Los Angeles is a bustling city with a population of over 10 million people. It is well-known that LA is not a haven of serenity, and noise pollution is a common issue faced by its residents. One significant contributor to the noise pollution in Los Angeles is air traffic. The city is home to several airports, including the Los Angeles International Airport (LAX), one of the busiest airports in the world. The constant takeoff and landing of aircraft at these airports generate significant noise, which affects nearby communities.
To mitigate the impact of aircraft noise on residents, LAX has implemented a procedure called "Over-Ocean Operations". This procedure requires aircraft landing at LAX between midnight and 6:30 a.m. to approach from over the Pacific Ocean whenever weather conditions and safe practices permit. This helps to reduce the noise experienced by communities east of the airport, such as Inglewood. However, even with this measure in place, aircraft noise continues to be a significant source of noise pollution in Los Angeles.
Aircraft noise can have significant impacts on the health and well-being of individuals living near airports. Research has linked noise pollution to various adverse effects, including high blood pressure, cardiovascular problems, anxiety, and poorer work and school performance. Sleep is particularly affected by noise, as even low-decibel interruptions can cause heart rate spikes and disruptions in REM sleep.
In addition to large commercial aircraft, smaller aircraft such as helicopters and private jets also contribute to noise pollution in Los Angeles. The LAPD operates the world's largest municipal airborne police force, with between 2 and 17 helicopters in operation daily from 8:30 a.m. to 4:30 a.m. These helicopters contribute to the overall noise levels in the city and can be particularly disruptive to residents.
Overall, air traffic is a major contributor to noise pollution in Los Angeles, affecting the quality of life and health of its residents. While measures such as "Over-Ocean Operations" at LAX help to reduce noise in certain areas, the high volume of air traffic in the city continues to present challenges in managing noise pollution.

Urban development and construction
The early morning and late-night construction works are particularly troublesome for residents, as the noise can interfere with sleep schedules. The Los Angeles Municipal Code includes regulations regarding early and late construction works, aiming to minimise the impact on residents. However, with the constant demand for urban development, construction sites are inevitable, and the associated noise pollution remains a challenge for many Angelenos.
In recognition of the problem, companies like Echo Barrier have introduced temporary acoustic barriers to screen noise on construction sites. These barriers aim to reduce the impact of construction noise on nearby residents, demonstrating a proactive approach to addressing this issue.
In addition to construction, urban development projects, such as road expansions and infrastructure improvements, also contribute to noise pollution. The sound of traffic, including cars, trucks, and motorcycles, is a constant backdrop to life in Los Angeles. The dense population and congestion on roads lead to higher levels of noise, with the 405 freeway being particularly notorious for its noise levels.
The impact of urban development and construction noise pollution goes beyond mere annoyance. Research has linked noise pollution to adverse health effects, including high blood pressure, cardiovascular problems, anxiety, and sleep disturbances. Therefore, it is essential for city planners and developers to consider the acoustic impact of their projects and implement measures to mitigate noise pollution wherever possible.

LAPD helicopters
Los Angeles, the city that never sleeps, is known for its noise. From the bustling roads to the ever-present hum of aviation, the City of Angels is a noisy metropolis. However, one of the most significant contributors to the city's noise pollution is the Los Angeles Police Department (LAPD) and their extensive use of helicopters.
With the world's largest municipal airborne police force, the LAPD keeps up to 17 choppers in the sky every day from 8:30 a.m. to 4:30 a.m. This constant presence of helicopters has led to numerous noise complaints from residents, who feel that their peace and quiet are constantly being shattered. The noise is so pervasive that it has even led to lawsuits, with the Stop LAPD Spying Coalition suing the LAPD for their flight records.
The LAPD's reliance on helicopters is often justified as a necessary tool for crime deterrence and patrolling the city's sprawling 4,700 square miles. However, the effectiveness of these helicopter patrols has been called into question, with some arguing that they are largely pointless and extremely wasteful. The climate impact of these short flights is significant, with the fleet's overall impact equivalent to adding 2,392 gas-powered cars to the roads. This is especially concerning in a county that already struggles with some of the worst air pollution in the United States.
The noise pollution caused by the LAPD helicopters has also been linked to negative health impacts. Research has shown that noise interruptions at night can lead to increased stress, high blood pressure, cardiovascular problems, anxiety, and poorer sleep quality. The constant presence of helicopter noise can disrupt the daily lives of residents, impacting their work habits and even the grades of students in school.
The LAPD's helicopter patrols have come under increasing scrutiny, with residents and advocates calling for more accountability and a reduction in pointless flights. The Automated Helicopter Noise Complaint System (ACS), a hotline for residents to voice their grievances, is one step towards addressing this issue.

Neighbours and noise complaints
Living in a bustling city like Los Angeles can mean that you are constantly surrounded by noise. From the roar of airplanes taking off and landing at LAX to the buzz of the city's famous nightlife, there are many sources of noise pollution in LA that can affect your quality of life. While some noise is to be expected in a busy metropolis, excessive noise from neighbours can be particularly disruptive and may even be illegal.
Noisy neighbours are a common issue in Los Angeles, and there are a variety of ways that they can create a disturbance. For example, loud music or parties, barking dogs, or even just a loud television or radio can all be sources of noise complaints. These types of noise complaints are typically handled by the local police station or the Noise Enforcement Team (NET), as the noise is often intermittent, occasional, or spontaneous. The LAPD non-emergency line can be reached at (877) ASK-LAPD (275-5273), while the NET can be contacted at 213-996-1250.
In the case of loud parties, it is best to call the non-emergency number and report the issue to the officers assigned to the area. If you are dealing with noise from construction, early deliveries, or trash pickups, the NET is the best point of contact. Barking dog complaints, on the other hand, must be submitted in writing to the City's Animal Care and Control Department, along with the name and address of the dog owner and a description of the issue.
It's important to remember that what constitutes unreasonable noise can vary depending on the time of day and the location. For example, in residential areas, the use of powered equipment or tools is not permitted between 10:00 pm and 7:00 am the following day. Additionally, no construction work is allowed between 9:00 pm and 7:00 am, and on Sundays or holidays. These rules are in place to ensure that residents can enjoy peace and quiet during certain hours of the day.
Noise pollution is more than just a minor annoyance; it can have significant impacts on health and well-being. Research has linked noise pollution to high blood pressure, cardiovascular problems, anxiety, and poorer work and school performance. Therefore, it is essential to address noise complaints promptly and effectively to maintain a healthy and peaceful living environment.
