Lullabelly utilizes safe sound level technology; maximum volume level is a safe decibel level similar to the volume level of a normal conversation (see sound decibel chart). For added safety, the Lullabelly speaker has a built-in volume control dial so, when using the dual adapter, the expectant mother can separately control the volume of her earphones and the volume of the music playing for her baby.

Lullabelly is the safer and more stylish alternative to holding headphones on your belly. By using Lullabelly, parents can create their baby’s playlist, AND listen along.

Unlike a standard set of headphones (made for an adults ears), the Lullabelly speaker’s maximum volume level is similar to a mother and father singing or talking direclty to their baby in the womb.

Using Lullabelly is about having fun, enjoying your pregnancy and exposing your baby to new experiences. Prenatal music stimulation should be used in moderation, starting around the third trimester, according to most experts. Moderation means no more than one hour at a time, and two to three times per day.

Ultrasound observations show that the fetus hears and responds to a sound pulse starting around 16 weeks of age; even before the ear construction is complete. The cochlear structures of the ear appear to function by the 20th week and mature synapses have been found between the 24th and 28th weeks.

Although a developing fetus can hear and react to sounds from as early as 16 to 20 weeks, active listening begins around the 24th week. For this reason, most formal programs of prenatal stimulation begin in the third trimester.
