The owner of a North Hollywood recording studio used by such artists as Linkin Park and John Fogerty filed a lawsuit Thursday against an adjacent exercise facility and its landlord, complaining that dropped weights and other heavy objects reverberate “like shock waves” through the plaintiff’s enterprise.
NRG Recording Services Inc. filed the lawsuit in Los Angeles Superior Court against Synapse Strength and Conditioning LLC and building owner Alfred Margoosian. The suit alleges negligence and interference with prospective economic relations.
The complaint also seeks a an order directing Synapse to “abate all conditions which cause the nuisance.”
NRG is owned by award-winning music producer Jay Baumgardner.
A man who answered the phone at Synapse said he would not have any immediate comment until he spoke with his attorney.
According to the lawsuit, NRG operates a “world class recording facility featuring two full tracking rooms and one mix/vocal room for multi- platinum level recording artists.” The business has been at 11128 Weddington St. for more than two decades, the suit states.
On Aug. 12, Synapse opened a cross-fit studio next to NRG, according to the lawsuit.
“The workouts and other activity at the North Hollywood Synapse involves … the banging, dropping and slamming of weights and heavy objects, which creates intense vibrations, extremely loud sounds and reverberations like shock waves that are felt and heard by NRG Studios within its premises,” the suit states.
NRG was designed with sound suppression measures so that even overhead flights from nearby Bob Hope Airport, the suit states.
However, the dropping of weights at Synapse can be heard at NRG and the noises are “akin to an explosion,” the suit states.
