California Noise Standards
The State of California has adopted official noise standards that require airports to monitor the amount of noise associated with aircraft at the airport. Bob Hope Airport publishes a Quarterly Noise Monitoring Report that documents the noise impact boundary of the Airport as defined in the Standards. The Airport will post the most recent of these reports on this website.
On February 28, 2008, the California Department of Transportation issued a decision granting the Airport Authority a variance from requirements of Section 5012 of the California Noise Standards, and pursuant to that decision, the Authority will publish updates regarding its Noise Impact Area Reduction Plan ("NIARP") and its Part 161 Study on this website.
Quarterly Noise Monitoring Reports:
Current Noise Contour
The noise contours shown here depict the boundary line between “compatible” and “incompatible” noise levels under the California Noise Standards. The contours are often misunderstood because some viewers assume the line is meant to show that there is no aircraft noise outside the contour. That is not the intent — clearly there is aircraft noise well beyond the contour boundary. However, under the state-prescribed standards, the average noise levels inside the contours are presumed to be so intrusive as to be incompatible with normal residential use. Outside the contour, the standards presume that average aircraft noise — even if it might be intrusive to some — is generally compatible with residential land use.
The noise contour maps show contours at two different noise levels: 70 decibels average noise over a 24 hour period (or 70 CNEL), and 65 decibels average noise over a 24 hour period (or 65 CNEL). CNEL stands for Community Noise Equivalent Level. Prior to 1986, 70 CNEL was considered to be the noise level at which noise and residential land use became incompatible. In 1986 the standard was changed to a quieter noise level, 65 CNEL, and the contours are shown at both levels in the interest of providing consistent data since the onset of ownership of Bob Hope Airport by the Burbank-Glendale-Pasadena Airport Authority in 1978.

Decrease in Noise Impact Area
While it is clear that there is still a significant noise impact area associated with Bob Hope Airport, it is equally clear that incompatible land use as determined by the California Noise Standards has been reduced dramatically since the airport was purchased from Lockheed in 1978. The following table lists, on an annual basis, the number of acres of incompatible land use due to aircraft noise at both the 70 decibel and 65 decibel levels under the state’s Community Noise Equivalency Level (CNEL) measurement system.
The standard for compatibility was 70 CNEL prior to 1986, and 65 CNEL thereafter. Although there are still some 20 acres of incompatible land under the 65 CNEL standard today, the Authority anticipates eliminating all incompatible land by the year 2015. See Noise Impact Chart to the right.
