What is the audio spotlight?

The Audio Spotlight is a revolutionary new audio technology that creates sound in a narrow beam, just like light. Aim the flat, thin speaker panel to your desired listening area, and provide all of the sound and none of the noise.™

People also ask, what is directional sound?

Directional sound is a technology that concentrates acoustic energy into a narrow beam so that it can be projected to a discrete area, much as a spotlight focuses light. When a sound beam is aimed at a listener, that person senses the sound as if it is coming from a headset or from “inside the head.”

What is a parametric speaker?

parametric speaker. A loudspeaker that people only hear when directly in front of it. Used for marketing or instructional purposes when someone walks by, parametric speakers use ultrasonic frequencies, which are extremely directional but are beyond human hearing.

What is HyperSonic sound?

HyperSonic Sound. This device used piezoelectric transducers to send two ultrasonic waves of differing frequencies toward a point, giving the illusion that the audible sound from their interference pattern was originating at that point. ATC named and trademarked their device as “HyperSonic Sound” (HSS).

What is a directional speaker?

Directional Sound refers to the notion of using various devices to create fields of sound which spread less than most (small) traditional loudspeakers. Several techniques are available to accomplish this, and each has its benefits and drawbacks.

What is hypersonic sound?

HyperSonic Sound. This device used piezoelectric transducers to send two ultrasonic waves of differing frequencies toward a point, giving the illusion that the audible sound from their interference pattern was originating at that point. ATC named and trademarked their device as “HyperSonic Sound” (HSS).

What did Woody Norris invent?

Woody Norris shows off two of his inventions that use sound in new ways, including the Long Range Acoustic Device, or LRAD. He talks about his untraditional approach to inventing and education, because, as he puts it: “Almost nothing has been invented yet.”

What is the hypersonic effect?

The hypersonic effect is a term coined to describe a phenomenon reported in a controversial scientific study by Tsutomu Oohashi et al., which claims that, although humans cannot consciously hear ultrasound (sounds at frequencies above approximately 20 kHz), the presence or absence of those frequencies has a measurable

Can listening to high frequencies damage your hearing?

The healthy human ear can hear frequencies ranging from 20Hz to 20,000 Hz. Over time, the hair cell’s hair-like stereocilia may get damaged or broken. If enough of them are damaged, hearing loss results. The high frequency area of the cochlea is often damaged by loud sound.

What is a low frequency sound?

Infrasound, sometimes referred to as low-frequency sound, is sound that is lower in frequency than 20 Hz or cycles per second, the “normal” limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high.

Can high frequency sounds make you sick?

Exposure to high-frequency sounds can make you sick. Increasing exposure to ultrasound in the air causes nausea, dizziness, migraine, fatigue and tinnitus.

Can you hear someone else’s ears ringing?

Most tinnitus is subjective, meaning that only you can hear the noise. But sometimes it’s objective, meaning that someone else can hear it, too. For example, if you have a heart murmur, you may hear a whooshing sound with every heartbeat; your clinician can also hear that sound through a stethoscope.

Can my tinnitus go away?

Tinnitus will probably just go away on its own. While tinnitus caused by a medication or other temporary situation may cease if that element is removed, the reality is that tinnitus does not just “go away” for most people.

Is tinnitus permanent?

Prolonged exposure to loud sounds is the most common cause of tinnitus. Up to 90% of people with tinnitus have some level of noise-induced hearing loss. The noise causes permanent damage to the sound-sensitive cells of the cochlea, a spiral-shaped organ in the inner ear.

Can you heal tinnitus?

Unfortunately, there is so far no scientifically proven cure or treatment for tinnitus. Ringing, hissing, buzzing, roaring – tinnitus can take many forms. The bothersome and uncomfortable noise in your ear varies from one tinnitus sufferer to another. So does the impact of tinnitus on people’s lives.

How do you test for tinnitus?

Tests include:

  • Hearing (audiological) exam. As part of the test, you’ll sit in a soundproof room wearing earphones through which will be played specific sounds into one ear at a time.
  • Movement. Your doctor may ask you to move your eyes, clench your jaw, or move your neck, arms and legs.
  • Imaging tests.
  • What is the best medication for tinnitus?

    For some, treatment with low doses of anti-anxiety drugs — such as Valium or antidepressants such as Elavil — help reduce tinnitus. The use of a steroid placed into the middle ear along with an anti-anxiety medicine called alprazolam has been shown to be effective for some people.

    Can you get tinnitus from stress?

    Ringing in the ears is a common symptom associated with stress and anxiety. We see this symptom a lot among anxious people. Stress-caused ringing in the ears is NOT a problem worth worrying about. In fact, worrying about it stresses the body, which can cause ringing in the ears to persist.

    What foods can make tinnitus worse?

    10 Foods That Will Make Your Tinnitus Symptoms Worse

  • Salt. Salt restricts blood vessels and increases blood pressure.
  • Smoking. OK, so it’s not technically a food but it is consumed so I shoe-horned it into the list.
  • Caffeine.
  • Sugar.
  • Sulfites.
  • MSG.
  • Quinine (tonic water)
  • Saturated and Trans Fats.
  • Can you stop tinnitus from getting worse?

    Anything you can do to limit your exposure to loud noise—by moving away from the sound, turning down the volume, or wearing earplugs or earmuffs—will help prevent tinnitus or keep it from getting worse.

    What vitamins are good for ringing in the ears?

    Lipoflavonoid is an over-the-counter supplement. It contains ingredients like vitamins B3, B6, B12, and C. Its main active ingredient is eriodictyol glycoside, which is the fancy word for a flavonoid (phytonutrient) found in lemon peels.

    Can anxiety make tinnitus worse?

    Tinnitus and anxiety. Additionally, much research has shown that while tinnitus can cause anxiety and stress, it also can be made worse by anxiety and stress: a vicious cycle. People with anxiety often perceive increased loudness of the ringing in their ears.

    How does the LRAD work?

    The LRAD’s job is to make sound – lots of sound. It produces very loud sound that is audible over relatively long distances. But it’s not limited to producing painful noise for use as a weapon. It can also amplify voices or recordings to a level that is loud and clear but not painful or debilitating.

    Can tinnitus be brought on by stress?

    Additionally, various emotional and physical factors have been linked to the onset of tinnitus, including stress. Although it is not always clear whether stress causes the onset of tinnitus, or perhaps is a contributing factor, it is common for tinnitus to start at times of high stress or after a period of stress.
