This is the most advanced sound therapy system with patented sound mixing technology that allows you to create 120 combinations of soothing nature sounds to ameliorate distracting noise and promote optimal relaxation, concentration, and sleep. Available in a black color offered only by Hammacher Schlemmer, the device has 18 primary sounds (like ocean surf and spring rain) captured in the field by leading nature recorders and, at the touch of a button, you can combine these with the soothing sounds of seagulls, songbirds, thunder, a fog horn, or loon calls. Incorporating years of neuroacoustic research, the device can layer the rhythmic sound of waves gently rapping against the shore with the choral rhapsodies of songbirds, or the sublime sound of thunderstorms with a powerful yet calming wind. Its patented Bio-Sync technology combats jet lag; non-linear music and slowed nature sounds reset the body's internal clock, helping you overcome ailments related to traveling through different time zones. Two integrated speakers and a subwoofer produce crisp, clear, balanced sound that is unrivaled by any other sound conditioner available. More than simply a sleep aid, the device is a full-featured alarm clock with voice recording capabilities, allowing you to rise to one of the soothing nature sounds or a verbal memo. Includes an AM/FM radio, headphone port, and a backlit digital clock. Plugs into AC. 8 1/4" H x 13" W x 6 1/3" D (3 3/4 lbs.)
