HYPER SONIC SOUND

WHAT IS HSS?• REVOLUTIONARY SOUND REPRODUCTION SYSTEM OF

THIS CENTURY

• LABS OF AMERICAN TECHNOLOGY CORPORATION,USA

• HSS IS A WAY FOR PROVIDING FOCUSSED SOUND JUST FOCUSSED LIGHT

HYPERSONIC

• RELATING TO SPEEDS OF MORE THAN FIVE TIMES THE SPEED OF SOUND

• RELATING TO SOUND FREQUENCIES ABOVE ABOUT A THOUSAND MILLION HERTZ

SOUND

SOUND IS A MECHANICAL WAVE

SOUND IS A LONGITUDINAL WAVE BECAUSE PARTICLES OF THE MEDIUM THROUGH WHICH THE SOUND IS TRANSPORTED VIBRATE PARALLEL TO THE DIRECTION IN WHICH THE SOUND WAVE MOVES

SOUND IS A PRESSURE WAVE

HOW IT HAPPENED ?• DISCOVERY AN ACCIDENT COMBINED WITH SOMETHING OF A STROKE OF

GENIUS IN 1996.

• ELWOOD NORRIS FROM AMERICAN TECHNOLOGY CORPORATION (ATC) WAS THE “INVENTOR” OR PIONEER OF HYPERSONIC SOUND IN THE UNITED STATES.

• WHILE INVESTIGATING THE NON-LINEARITY GENERATED DIFFERENCE SIGNAL, HE DISCOVERED THAT WHILE PRODUCING A SIGNAL ABOVE THE RANGE OF HEARING AND INTERFERING IT WITH ANOTHER SIGNAL THAT IS SLIGHTLY GREATER THAN THE FIRST, AN AUDIBLE DIFFERENCE SIGNAL WILL RESULT.

• THE RESULTANT SIGNAL WAS COMPARABLE TO BEATS, WHICH ARE CREATED DURING THE CONSTRUCTIVE AND DESTRUCTIVE INTERFERENCE OF LINEAR WAVES.

HOW IT HAPPENED ?

• NORRIS WAS PUZZLED UNTIL HE REALIZED THAT BY SENDING BOTH SIGNALS THROUGH ONE TRANSDUCER IT WOULD ELIMINATE ALL POSSIBILITIES OF LINEARITY.

• AFTER THIS IT WAS PROVED THAT SOME NON-LINEARITY IN AIR WAS THE ACTUAL CAUSE OF THE AUDIBLE FREQUENCY PRODUCED IN THE EXPERIMENT.

• THESE EXPERIMENTS LEAD TO THE CREATION OF HYPERSONIC SOUND

PRINCIPLE

HYPERSONIC SOUND SYSTEM RELIES ON THE DIFFERENCE IN FREQUENCY DEVELOPED WHEN TWO HIGH-AMPLITUDE ULTRASONIC SIGNALS, 1,000 HZ OR SO APART, GENERATE SOUNDS THAT SEEM TO THE HEARER AS IF THEY HAVE COME OUT OF THIN AIR

• THE SPEAKER SENDS OUT AN ULTRASONIC SIGNAL.

• THIS SIGNAL INTERACTS WITH THE AIR AND BREAKS INTO 3 SURROUNDING SIGNALS.

• ONE OF WHICH IS THE AUDIBLE SIGNAL. THIS SIGNAL GETS “TRAPPED” BY THE OTHER 2 SIGNALS IN A SOUND “CONE.”

• THIS CONE ENABLES THE SOUND TO TRAVEL LONG DISTANCES WITHOUT DISPERSION.

GIST

• A REGULAR SPEAKER CREATES SOUND BY CONVERTING AN ELECTRICAL SIGNAL INTO AUDIO VIA A VIBRATING DIAPHRAGM AND SENDS THE AUDIO INTO ALL AREAS THAT ARE IN THE SURROUNDING AREA OF THE GENERAL DIRECTION OF THE SPEAKER CONES

• THE HYPERSONIC SOUND SYSTEM EMITS A NARROW BEAM OUT SO THAT ITS SOUND CAN ONLY BE HEARD BY A PERSON IN THE DIRECT PATH OF THE BEAM OR IN A LOCATION WHERE THEY CAN HEAR THE SOUND REFLECTED FROM A VIRTUAL SURFACE

• THE DIFFERENCE IS THAT THE SOUND FROM A TRADITIONAL SPEAKER SPREADS OUT AND DISPERSES, FALLING OFF QUICKLY WHILE THE HYPERSONIC SOUND IS STRONGER AT GREATER DISTANCES, BECAUSE IT IS MORE DIRECTIONAL, AND DIRECTIONAL SOUND IS ALWAYS STRONGER

NORMAL vs HSS SPEAKER

ADVANTAGES• DELIVER SOUND TO PHY IMPOSSIBLE AREAS

• ULTIMATE CONTROL OF AUDIO PLACEMENT

• MINIMIZES NOISE POLLUTION

• EASE OF INSTALLATION

• THIN AND FLAT AND DO NOT REQUIRE A MOUNTING CABINET

• TRAVELS MUCH FARTHER IN A STRAIGHT LINE THAN CONVENTIONAL LOUDSPEAKERS

• DIRECT CONTACT TO RAIN OR SNOW

• WATER

RESTRICTIONS

• MUSEUMS, AQUARIUMS, ZOOS, MONUMENTS ETC

• AIRPORTS, RAIL LINES, BUSSES, COMMUTER TRAIN STATIONS, OR PORT TERMINALS

• TARGETED, UNOBTRUSIVE ADVERTISING DIRECTLY AT THE POINT OF PURCHASE

• AUTOMOBILES

• AUDIO/VIDEO CONFERENCING

• PORTABLE “BULL HORN” TYPE DEVICE FOR COMMUNICATING WITH A SPECIFIC PERSON IN A CROWD OF PEOPLE

APPLICATIONS

MILITARY APPLICATIONS

LRAD PROVIDES MILITARY PERSONNEL THE CAPABILITY TO TRANSITION THROUGH THE RULES OF ENGAGEMENT TO DETERMINE A TARGET'S INTENT, AND ALSO PROVIDES GREATER ASSURANCE THAT INNOCENT LIVES ON BOTH SIDES OF THE DEVICE ARE NOT LOST DUE TO MISCOMMUNICATION

MILITARY APPLICATIONSHIGH DIRECTIONALITYREDUCES THE RISK OF EXPOSING PERS TO UNDESIRED AUDIO LEVELS

HIGH DECIBEL OUTPUT CLEAR COMMUNICATION

COST EFFICIENCY • INCREASED SECURITY COVERAGE • REDUCED MANPOWER • INCREASED OPERATIONAL EFFICIENCY • INCREASED RESPONSE CAPABILITIES

EASE OF INSTALLATION • LOW POWER REQUIREMENTS • WEATHERPROOF • LIGHTWEIGHT • FLEXIBLE MOUNTING

LRAD

A CLOSER LOOK

PLACED ON LISTENING STATIONS, THE SOUND DOMES PROVIDE A PERSONAL STEREO EXPERIENCE FOR THE CUSTOMER AND UNLIKE SHARED HEADPHONES, THERE ARE NEVER ANY HYGIENE ISSUES TO DISCOURAGE CUSTOMERS FROM ENJOYING THE AUDIO PRESENTATION. CUSTOMERS CAN STAND NEXT TO EACH OTHER AND SAMPLE DRASTICALLY DIFFERENT MUSIC STYLES WITHOUT THE SPILLOVER OF NORMAL SPEAKERS.
