Sound Absorption
That tiny crack that runs around your door transmits more sound than you would know.
Noise is a daily occurrence that we all endure to a certain degree from noisy kettles, screaming children, loud TVs and the deafening thud of a bass. There’s sometimes little peace in ones day. Ongoing excessive noise is not only aggravating it can actually be harmful to your ears and has a significant impact on the way our spaces work in the home.
When it comes to residential design, the acoustics, (the way in which the structural characteristics of a space relate to how well sound can be heard) although a key design feature, are rarely considered during the building process and sometimes only tackled during a renovation.
Soundwaves seep through doors, windows, ceilings and cracks, so how do you reduce unwanted sound from affecting your day to day activities?
Hard flat surfaces tend to bounce sound waves around, sometimes creating a lasting echo effect if the surfaces are parallel walls. The softer and less uniform the surface, the less opportunity sound has to bounce off. Textiles, including drapery and upholstered furniture and furnishings not only deliver a design aesthetic they also play a significant role in the absorption of sound.
However not all textiles have equal sound absorption qualities however. The level of sound absorption is dependent upon a textile’s weight, composition, and/or construction. Generally (due to the large vertical mass) drapery provides the main textile source of sound absorption however, there are several other ways to achieve this.

Poll: If we want to reduce speeding, what do you think actually changes driver behaviour? 🛻🚨🚓
In the Post's article on speeding penalties, the question is asked whether speeding fines are truly about road safety, or are they just a way to boost revenue for the Crown?
What do you think? Should speeding motorists receive speeding fines or demerit points?
-
40.7% The sting of a fine (Money talks!)
-
59.3% The threat of demerit points (Nobody wants to lose their license!)
SLASH BESIDE THE TRACK UP TO TRIG
I question the wisdom and the morality of an industry which creates so much waste, waste which is also a cause of widespread and devastating damage. So, I searched the internet for potential uses of slash. It was easy to find.
I recommend a visit to nzbioforestry.co.nz. I quote from the website:
OUR SOLUTION:
NZ Bio Forestry proposes to develop a sustainable renewable forestry model that increases the economic value of the NZ- Aotearoa forestry sector, simply by integrating bio-technologies augmenting the forestry, wood manufacturing, and petrochemistry industries into one model.
Specifically, our strategy is to utilise the whole tree and convert the tree’s sugars into bioenergy, biomaterials, and biochemicals. This means using slash, off cuts, pruning, and wood waste to produce biofuel via bio pellets and biochemicals. It means optimising logs through the whole process….logging, manufacturing freighting, and refining process to serve the many Asia-Pacific markets with high-value products….not just exporting raw logs to one or two large dominant markets! (End of quote)
NZ Bio Forestry then contrasts the financial return from the present exports of raw logs with the potential return from utilising the WHOLE TREE.
In US dollars, the return from exporting logs is between $50 - $140 per log.
Using the whole tree including the slash and other waste for wood processing would return $200 - $800 per tree, and,
Using the bio-refinery process to convert the wood waste into fossil-free biochemicals would return $2,500 - $11,200 per tree.
I can’t help but conclude that our current focus on exporting logs is a pitiful failure of industry and government policy compared with the potential benefits of processing THE WHOLE TREE. And to complete the argument, this not just theory. In Scandinavia, SCA, which owns Europe’s largest private forest with 2.7 million hectares, has built a well-invested value chain that maximises the value of each individual tree and all of the forestry’s resources.
A SUMMARY OF POTENTIAL ADDITIONAL PRODUCTS:
Wood Pellets and Chips: Slash can be collected, dried, and processed into hog fuel or wood pellets for use in industrial boilers, as a replacement for coal, to generate heat and electricity.
Biofuel Production: Research is underway to convert forest residues into marine biofuel to help decarbonize the shipping sector.
Gasification: Advanced, small-scale, on-site processing plants can turn slash into renewable energy products like bio-oil, ethanol, and hydrogen.
Biochemicals: Specialized refineries can convert woody waste into sustainable alternatives to plastics, chemicals, and industrial products.
WAKE UP Aotearoa, New Zealand!!!
