Sleep is that golden chain that ties health and our bodies togetherThomas Dekker
Laugh and the whole world laughs with you. Snore and sleep alone.Anthony Burgess
Harsh sounds put us on edge, while room which is soft and quiet tells our brains it’s time to unwind and relax. The illustration on the left shows how sound directly impacts on you when you lie down to sleep.
In terms of architectural acoustics, the surface closest to our ears that will have the most influence on what we hear (other than a direct sound signal) simply because of proximity. When we sleep, the wall behind the bed or headboard is the surface closest to our ears. As seen in the image above, if this surface is highly reflective to sound, those reflections will bounce back to our ears & can potentially disturb our sleep.
The very same principle that caused a sound problem in the above scenario, can be harnessed for our well-being, with the aid of proper acoustic design. By utilizing specially designed and tested materials, Genesis Acoustics has designed an Acoustic Headboard that works for you, to maximize the sound absorption where it matters most.
In the illustration above, the headboard looks like a raw, rustic timber but it is in fact an Acoustic Headboard, soft to the touch but with the beauty of wood. According to the department of health in the UK, acoustic design is even fundamental to the quality of healthcare buildings.
Sound affects us both physiologically and psychologically. Noise, which can be defined as “unwanted sound”, can increase heart rate, blood pressure, respiration rate and even blood cholesterol levels.
Good acoustic conditions promote essential sleep patterns. Such conditions are key to healing.
Snoring can test even the most loving relationship whether it be siblings who share a room, parents or a couple. Snoring can cause frustration and wear down our coping mechanisms.
According to the National Sleep Foundation, 39 percent of American adults get less than seven hours of sleep each weeknight, and more than one in three (37 percent) are so sleepy during the day that it interferes with daily activities. The sleep loss associated with snoring — whether it’s the snorer or the bed partner who is awakened by the snoring, interrupts important recuperative sleep, which can impair a person’s ability to perform cognitive tasks involving memory, learning, reasoning and mathematical processes. It can impair motor skills and can cause morning headaches, irritability, burnout and depression, to mention just a few symptoms.
A hard resonant surface e.g. A drywall, plastered brick wall, face brick, timber headboard etc directly behind the bed will reflect sound waves back to the position of the person sleeping. Conversely having a sound absorbing product behind the bed will reduce the sound reflections, making for a quieter place, where it is easier to rest.
Sound absorption coefficients vary considerably depending on the type, thickness and density of the product. Furthermore there is no magic formula as to what produces better sound absorption, the density and thickness that produces good sound absorption for one material type might produce very different results for another type of material, nor is it possible to say that a lower / higher density will always produce the desired result. Therefore the only way to know for sure what the sound absorption properties of a product are is to view certified results, obtained by an objective third party testing facility.
Such results will display the actual sound absorption coefficient at 1/3 octave bands from which a noise reduction coefficient can be calculated. This is of special interest because sound is not absorbed equally at all frequencies. Ideally, you want a sound absorption that rises steeply from the lowest tested frequency at 125Hz, peaking at between 500Hz to 1000Hz and continuing steadily without any dips through 4000Hz which is typically the highest frequency tested.
Below is the sound absorption for the Acoustic Headboards by Genesis Acoustics
An average of 95% sound absorption is achieved overall, this means that if you have been sleeping with a hard wall behind your bed, with an Acoustic Headboard by Genesis Acoustics, you could experience a huge improvement in reduced sound levels and certainly a much softer, quieter sound when lying down to sleep.
The sound absorption figures quoted do not refer to the % reduction of the sound in the whole room, they refer to the % absorption of sound striking the Acoustic Headboard
Noise reduction coefficient (NRC): The arithmetic average, to the nearest multiple of .05, of the sound absorption coefficients in the 1/3 octave bands centered at 250Hz, 500Hz, 1000Hz, and 2000Hz. The number ranges from NRC 0.5 (minimum) to NRC 1.0 (maximum achievable). As an example an NRC 0.5 equals an average of 50% sound absorption between 250 – 2000Hz.
