Hearing Loss: The Invisible Disability - Is your facility ADA Compliant? 
Almost anyone can easily explain the purpose of a wheelchair ramp, wheelchair signage on doors, or signs translated into Braille. Less known are the effects of the "invisible disabilty", also known as hearing loss. In 2012, legislation went into effect that requires all new construction and renovations to meet enhanced ADA standards for assistive listening sytems. Listen Technologies has published a white paper outlining these new requirements that you can DOWNLOAD NOW. 

Thinking Outside the Box with ListenIR - SIMPLY BRILLIANT

ListenIR systems use infrared light to transmit audio, much like a television remote control. An IR system is made up of a radiator, transmitter, and receiver. Unlike RF systems, an IR system incorporates line-of-sight technology, and is therefore very secure for confidential transmission fo the audio signal within a room. Listen LT-84-01The ListenIR system is great for classrooms, corporate boardrooms, courtrooms and wherever a private audio signal is needed. Because of its versatility, ListenIR can be used for a wide range of unique applications. Listen Technologies has detailed many of these ideas in this blog that you can read here...

Ellyson Field WWII era

Editor's Note: Pro SVL is located in Ellyson Industrial Park, an area that is rich in naval aviation history relevant to our country’s involvement in WWII, the Korean War, and the Vietnam War. Our office complex is situated to the east of what was once an active runway, parts of which can still be seen today. If you look closely at the present-day map (below), you can see parts of the old runway 7B as it cuts a diagonal swath under the building just south of Pro SVL. The black-and-white photo (left) shows Ellyson Field looking toward the west. The three hangars mentioned in this article can be seen in the upper right corner of the photo.

We are enthused to call this area home, and we thought that it would be an interesting aside to include a brief history of NAS Ellyson Field as a footnote to our About Us page. Perhaps you or someone you know once served as a naval aviator at this very location.


Every day when we come to work, we pass three former aircraft hangars and an administration building that is topped with what was once an aircraft control tower. We also see remnants of helicopter landing pads and runways for fixed wing aircraft. These buildings and artifacts serve as silent reminders of a storied past when this area echoed with the sound of planes and helicopters flying overhead.

In 1940, prior to our country’s involvement in WWII, the Navy purchased open farmland 16 miles northeast of NAS Pensacola. Originally designated Base Field 01913 (Site 3), the site was equipped with a hangar and a repair unit. With the escalation of the war in 1941, the Navy decided to expand Site 3 from an auxiliary airfield into a larger facility for increased flight training. Renamed Ellyson Field in honor of CDR Theodore G. “Spuds” Ellyson, the Navy’s first aviator, training flights began on the afternoon of October 1, 1941.

For the duration of the war, Ellyson Field was used as an intermediate basic training base for Navy pilots. At one point, almost 250 Vultee SNV (“Vibrator”) single engine monoplanes were being used for flight instruction which included 36 hours of overall flying time, both day and night. Eventually, the SNVs were replaced by other aircraft. Advanced students proceeded on to specialized intermediate courses using SNJ, PBY, SNB and OS2U aircraft.                     

Ellyson Field 1943In 1943, Ellyson Field was officially designated as an NAAS (Naval Auxiliary Air Station). By 1945, an Intermediate Instructor School and a Gunnery Instruction Unit had been added to the curriculum at Ellyson. When the war ended later that year, Ellyson Field was placed in reduced status and all training functions were re-assigned to Corpus Christi, Texas.

During that period, parts of the base were opened for civilian use. A school for handicapped children was opened along with a training center for the Brooklyn Dodgers baseball team.

Idle for five years, Ellyson Field began to see new life in late 1950. The Korean War was escalating, and the helicopter was proving its worth in the combat zone. Realizing the need for pilots, the Navy decided to reopen Ellyson Field as a helicopter pilot training school. Ellyson Field once again became a beehive of activity with the first class beginning its eight weeks of training on January 15, 1951.

Helicopter hovering over main gate Ellyson FieldThe intense eight-week program included 60 hours of flight training and 35 hours of ground school. Initially, all training flights were conducted within the field boundaries except for some advanced instruction. As the training progressed, students moved to larger, more advanced helicopters to complete their schooling.

During the 1960s, NASA sent 14 of its 15 original astronauts to Ellyson Field for specialized flight training. NASA also brought in a Lunar Excursion Module simulator that was part of the Project Apollo lunar landing program.

Eventually, Ellyson Field was obliged to shut down its operations due to continuing conflicts with commercial aviation traffic at the nearby Pensacola International Airport. The base was declared a non-aviation facility in 1973 and was permanently closed in 1979.

Although the planes and helicopters may be gone today, Ellyson is still a beehive of activity. In its second life as an industrial park, Ellyson is now home to many thriving businesses. Remnants of the original airfield can be seen everywhere, and if you listen carefully on a clear day you can still hear the sounds of planes – echoes from a not-too-distant past.
