With the alarm clock from Bellman & Symfon of the Classic series you can wake up with a very loud sound (over 100dB gradually) and a vibration unit that is placed under your pillow.

The sound emitted by the device, in addition to being very loud, is also of alternating frequencies. It has a large LCD screen with adjustable brightness and the option to completely remove the wake-up sound, and wake up only from the vibrating unit under your pillow.
