Quick Facts
- Airport noise zones are designated areas around airports where noise levels are measured and regulated.
- The Federal Aviation Administration (FAA) is responsible for establishing and enforcing noise standards for airports in the United States.
- Noise zones are typically categorized into different tiers based on the level of noise exposure, with Zone 1 being the quietest and Zone 4 being the noisiest.
- The Day-Night Average Sound Level (DNL) is a common metric used to measure noise exposure in airport noise zones.
- DNL levels are calculated by averaging sound levels over a 24-hour period, with nighttime levels weighted more heavily than daytime levels.
- Airport noise zones can impact property values, with homes and businesses in noisier zones often experiencing reduced property values.
- The FAA requires airports to develop and implement noise mitigation plans to minimize the impact of noise on surrounding communities.
- Noise mitigation measures can include soundproofing, noise barriers, and flight path changes.
- Some airports offer noise-compatible land use planning, which involves designating certain areas for noise-tolerant uses such as industrial or commercial development.
- The Airport Noise and Capacity Act of 1990 provides a framework for managing airport noise and balancing the needs of airports, airlines, and surrounding communities.
Airport Noise Zones 101: Understanding the Impact on Hawaii Real Estate
Airport noise zones are areas surrounding an airport that are affected by the noise generated by air traffic. The noise levels are measured in A-weighted decibels (dBA), which is the most common way to quantify sound. The Federal Aviation Administration (FAA) has established guidelines to ensure that airport noise does not disturb the surrounding communities. The guidelines are based on the noise exposure map, which divides the surrounding area into zones.
Breakdown of Different Airport Noise Zones
| Zone | Noise Level (dBA) | Description |
|---|---|---|
| A | 65-70 | High noise exposure, closest to the airport |
| B | 60-65 | Medium-high noise exposure |
| C | 55-60 | Medium noise exposure |
| D | 50-55 | Low-medium noise exposure |
| E | <50 | Low noise exposure |
Impact on Hawaii Real Estate
In Hawaii, the noise generated by airports can significantly impact property values. For example, a study by the University of Hawaii found that properties near Honolulu International Airport had lower property values due to the noise generated by air traffic. The study found that for every 1 decibel increase in exposure, property values decreased by 0.5%.
Tips for Homebuyers and Real Estate Investors
When buying or investing in real estate near an airport, it’s essential to consider the airport noise zones. Here are some tips:
- Research the airport noise zones: Understand the different zones and how they impact property values.
- Visit the property: Visit the property during different times of the day to get a sense of the noise level.
- Work with a local real estate agent: A local agent can provide valuable insights into the impact of airport noise on property values.
Noise Mitigation Measures
Airport noise mitigation measures can significantly reduce the impact of airport noise on surrounding communities. These measures include:
- Soundproofing: Installing soundproofing materials, such as insulation and acoustic panels, can help reduce noise levels.
- Land use planning: Ensure that residential areas are not located directly under flight paths.
- Noise barriers: Building noise barriers, such as walls or screens, can help reduce noise exposure.
Case Study: Kahului Airport
The Kahului Airport on Maui is a great example of how airport noise mitigation measures can benefit surrounding communities. In the 1990s, the airport implemented a noise mitigation program, which included soundproofing of homes and the construction of noise barriers. The program was successful in reducing noise levels, and property values in the surrounding area increased.
Frequently Asked Questions
Frequently Asked Questions About Airport Noise Zones
- Q: What is an Airport Noise Zone? A: An Airport Noise Zone is a designated area around an airport where aircraft noise levels are higher due to aircraft takeoffs and landings.
- Q: How are Airport Noise Zones determined? A: Airport Noise Zones are determined by measuring the noise levels at various points around the airport and mapping the areas with higher noise levels.
- Q: What are the different types of Airport Noise Zones? A: The most common types of Airport Noise Zones are:
- Quiet Residential Area (QRA)
- Non-High Noise Exposure Forecast (N-HNEF) Area
- High Noise Exposure Forecast (HNEF) Area
- Q: What are the noise level thresholds for each Airport Noise Zone? A: The noise level thresholds are as follows:
- QRA: 65-70 DNL (Day-Night Average Sound Level)
- N-HNEF: 70-75 DNL
- HNEF: 75 DNL or above
- Q: How do I know if my home is located in an Airport Noise Zone? A: Check with your local airport administration or visit their website to find out if your home is located in an Airport Noise Zone. You can also check with your local government or zoning department for information.
- Q: Are Airport Noise Zones the same as Noise Abatement Zones? A: No, while the terms are sometimes used interchangeably, Noise Abatement Zones (NAZs) are specific areas where noise-producing activities are restricted to reduce noise levels. Airport Noise Zones are broader areas where noise levels are higher due to aircraft operations.

For Buyers and Sellers
Personal Summary: Understanding the Impact of Airport Noise Zones on Home Buyers and Sellers
Airport noise zones can significantly impact home buyers and sellers. While properties in these zones may offer lower prices, they also come with noise-related drawbacks that can negatively affect the quality of life and property value. Thorough research, professional guidance, and open communication can help buyers and sellers navigate the complexities of airport noise zones and make informed decisions about their real estate investments.
Impact on Home Buyers:
- Lower Property Values: Homes located in airport noise zones typically have lower property values compared to similar properties in quieter areas.
- Disturbances and Disruptions: Frequent air traffic can lead to constant noise, disrupting daily life and making it challenging to enjoy the outdoors or relax in one’s own home.
- Health Concerns: Exposure to prolonged noise pollution has been linked to mental health issues, cardiovascular problems, and decreased quality of life.
- Future Planning: Homebuyers should consider the potential for airport expansion or increased air traffic, which could further exacerbate noise issues.
Impact on Home Sellers:
- Discounted Pricing: Properties in airport noise zones may be priced lower to account for the negative impact of noise on their value and appeal.
- Difficulty Selling: Homes in noisy areas may be less attractive to potential buyers, making it harder to sell the property.
- Noise Disclosure: Sellers are often required to disclose the presence of airport noise zones, which can be a significant turn-off for buyers.
- Investor Appeal: Some investors may view properties in airport noise zones as a worthwhile investment opportunity, given the potential for affordable prices and rental yields.
