RINGMAX’s Volume & Frequency Range Superiority:
The most common type of hearing loss affects chiefly the higher sound frequencies. The left chart graphs a
typical loss profile of this kind. The shaded area indicates the optimal ring frequency range, 250–1000 Hz,
where hearing ability is maximized. On the right is a sound pressure diagram. The blue area maps the RINGMAX volume (maximum sound energy) at its four tone settings, while the lower mark indicates the lesser volume and inappropriate frequency range of normal telephone ringers.
