6 Large Angeles Brand Referee Whistles for Safety

Angeles Whistle — Technical Specifications

Brand: Angeles

Materials and Construction

Main body: made of high-quality, thermoset material that provides rigidity, resistance to constant use, heat, and humidity. Does not easily deform with climate changes.

Cap or sound output nozzle: composed of resistant polymer, black in color, with a smooth and polished finish.

Internal spherical element: Styrofoam ball with an approximate diameter of 15 mm, replaceable, which interrupts the airflow to generate the oscillation and characteristic sound.

Chain/ring: for attaching to a uniform, belt, or wearing around the neck.

Acoustic Performance

Sound intensity: approximately 120 dB, sufficient to be audible in noisy environments, traffic, or open spaces.

Frequency/tone: high-pitched, loud, and clear sound, designed to capture immediate attention.

Large size: designed for a firm grip even with gloves, with a robust mouthpiece and an easy-to-hold body.

Maintenance: the inner ball can be replaced, extending the whistle's lifespan.

Typical Applications

Urban traffic and traffic police: signaling, vehicle control, and clear commands in noisy environments.

Sports and refereeing: calling fouls, stopping play, starting times.

Private security and emergency brigades: ideal due to its sound level and material resistance.

Limits and Technical Considerations

Resistance: although the plastic is strong, it can fracture from very hard impacts.

Sound level: 120 dB can cause hearing discomfort if used too close to the ear.

Water resistance: not completely watertight; humidity can affect the internal ball
