The fifth generation of Safe Volume Technology innovation and upgrade

The iClever Safe Volume Technology has evolved through five generations:

• First generation 85dB: Refers to a single frequency point.
• Second generation 85dBA (Laeq/pink noise): Measures the spectral intensity of the entire sound, applying an A-weighting correction curve for the average value.
• Third generation of cochlear resonance pre-attenuation: Attenuates sound likely to cause hearing impairment (2kHz-4kHz sound waves) by 5-10 decibels, protecting high-frequency hearing loss while maintaining clarity.
• Fourth generation circuit control: Enables 85dBA volume control for any equipment.
• Fifth generation decibel meter: Displays the sound decibel level on the screen.
