187196Hz

187196Hz is a specific frequency equal to 187,196 cycles per second, or 187.196 kilohertz. It lies well above the upper limit of human hearing, which typically ends near 20 kilohertz. As a result, the frequency is inaudible to humans but can be detected and measured with appropriate electronic instrumentation.

The frequency is used in several high‑frequency technological applications. In medical ultrasound imaging, transducers frequently operate in the 2‑15 megahertz range, but lower‑frequency diagnostic devices such as some Doppler probes can use frequencies in the 100‑200 kilohertz band. In these applications, 187kHz can be employed for superficial tissue imaging or blood flow measurement where lower attenuation is required. In industrial nondestructive testing, ultrasonic flaw‑detection ranges from 100 to 500 kilohertz, and 187 kHz is a suitable value for detecting cracks or inclusions in metals and composites. Sonar systems used for underwater mapping or fish‑finders also make use of frequencies in the 100‑300 kilohertz range; this frequency is well suited to balancing resolution with propagation distance in clear water.

The frequency can also be found in certain communication and synchronization contexts. Electronic clocks often use high‑frequency oscillators for timing reference, and 187.196 kHz could be a tuning frequency for a crystal oscillator in an older radio or analog computing system. In the field of physics, 187.196 kHz corresponds to a photon of energy 0.776 electron‑volts, which can be relevant in certain spectroscopic measurements.

Because it is an ordinary numeric value rather than a named unit or phenomenon, 187196Hz does not receive the same recognition as standard audio frequencies or radio bands, but it remains a component of any system that requires precise, high‑frequency reference signals.
