<p><span style="font-size:14px;"><em>(Excerpt from Special Feature: Hypersonic Effect, Science Journal Vol. 83 No. 3, 2013)</em></span></p>

<p><span style="font-size:14px;">The <strong>Hypersonic </strong><span style="box-sizing: border-box; margin: 0px; padding: 0px;"><strong>Effect</strong></span> phenomenon, where ultrasonic waves above 50 kHz, imperceptible to the human ear, exert remarkable effects on the brain and body, was discovered by musician/physicist <strong>Tsutomu Ohashi</strong> and validated through studies showing <strong>α-wave enhancement</strong>, <strong>immune-boosting effects</strong>, and <strong>stress hormone reduction</strong>.</span></p>

<p><span style="font-size:14px;"><strong>G-Star Sounds LLC</strong> is pioneering its application through innovative instrument development for the 2025 Osaka-Kansai Expo, themed <span style="color:#c0392b;"><strong><em>"Designing Future Society for Our Lives"</em></strong></span>.</span></p>

<h2><span style="font-size:14px;">The Mechanism of "Inaudible Sound"</span></h2>

<p><span style="font-size:14px;">The Hypersonic Effect’s core lies in <strong>direct brain activation via skin and bone conduction</strong>. Ultrasonic waves above 40 kHz are detected not by the ears but through the <strong>body’s surface</strong>, stimulating the <strong>"core brain"</strong> (brainstem, thalamus, and hypothalamus)-the hub of life-sustaining functions.</span></p>

<p><span style="font-size:14px;">This activation leads to:</span></p>

<ul>
	<li>
	<p><span style="font-size:14px;"><strong>Relaxation</strong>: Parasympathetic dominance reduces stress hormones like cortisol.</span></p>
	</li>
	<li>
	<p><span style="font-size:14px;"><strong>Immunity Boost</strong>: Natural killer cell activity increases, enhancing viral defense.</span></p>
	</li>
	<li>
	<p><span style="font-size:14px;"><strong>Focus Enhancement</strong>: Sustained α-waves and improved prefrontal cortex blood flow.</span></p>
	</li>
</ul>

<h2><strong><span style="font-size:14px;">Nature’s Hidden Sound Therapy</span></strong></h2>

<p><span style="font-size:14px;">Natural environments rich in ultrasonic frequencies-such as <strong>waterfalls (80 kHz+)</strong>, <strong>Balinese gamelan</strong>, <strong>Japanese shakuhachi</strong>, and <strong>biwa lutes</strong>-demonstrate this effect. These sounds, now scarce in urban life, are gaining attention for their <strong>restorative potential.</strong></span></p>

<h2><strong><span style="font-size:14px;">G-Star Sounds’ Innovation</span></strong></h2>

<p><span style="font-size:14px;">[unscaled5]</span></p>

<p><span style="font-size:14px;">Under the vision <strong>"Bringing Hypersonic Sound to Daily Life"</strong>, </span><strong><span style="font-size:14px;">G-Star Sounds</span></strong><span style="font-size:14px;"> is developing instruments that retain traditional forms (e.g., pianos, guitars) while emitting <strong>ultrasonic waves above 50 kHz</strong>. A groundbreaking performance using these instruments is scheduled for <strong>June 26, 2025, 15:30</strong> at the Osaka-Kansai Expo’s TEAMEXPO Pavilion.</span></p>

<p><strong><span style="font-size:14px;">G-Star Sounds </span> is also actively seeking partners interested in:</strong></p>

<ul>
	<li>
	<p><strong>Hypersonic conversion of existing music</strong></p>
	</li>
	<li>
	<p><strong>Manufacturing hypersonic instruments</strong></p>
	</li>
	<li>
	<p><strong>Developing hypersonic audio devices</strong></p>
	</li>
</ul>
