Since we first learned to record sounds on wax tubes that could be played back on phonographs, humanity has come a long way. While setting up one of these antique music players and hearing what audio enthusiasts listened to in the late 1800s is interesting, it pales in comparison to the advances we've made. What are some of the most exciting recent acoustic engineering advances, and what does the future of acoustic engineering look like?
Recent Audio Engineering Advances
Inflatable concert halls have appeared in the most unexpected places, providing sound engineers with the perfect canvas to create the ideal stage for musical acts. Once the structure has been inflated and is ready to go, sound engineers can manipulate the interior acoustics in the same way.
Acoustic engineers can use 3D impulse response management to create a 3D visualization of a room's acoustics using a set of microphones. This makes it easier to identify problem areas that would otherwise be difficult to identify with the human ear.
Adding augmented or virtual reality to the mix introduces the practice of acoustic holography, which allows engineers to create a picture of the sound patterns in real-time. This could be useful for engineers concerned about noise pollution as well as those attempting to create the ideal acoustics for a musical performance or play.
What Does the Future Hold for Acoustical Engineering?
It's exciting to see how far the acoustical engineering industry has come, and even more exciting to see what the future may hold. What do acoustical engineers hope to achieve?
Acoustic Metamaterials
Gesture Control
3D Audio
Music Recordings
Although many people are unfamiliar with the term "acoustic engineering," it is a type of engineering that most people are likely to encounter on a daily basis. The future of acoustical engineering is bright, and we'll most likely see a lot of changes that make it easier to immerse ourselves in the perfect audio experience over the next few decades.

The new UK Infrastructure Bank (UKIB) recently opened, with its remit confirmed by the UK government in a new Framework Document.
The document sets out the role of the bank as providing: "leadership to the market in the development of infrastructure and new infrastructure technologies, crowding-in private capital and reducing risk through its cornerstone investments and range of financial products. It will bolster the government’s lending to local government for large and complex projects through its expertise and scrutiny, and help to bring private and public sector stakeholders together to regenerate regions and create new opportunities."
It will have two strategic objectives, to help tackle climate change and support regional and local economic growth. Given these two objectives may conflict, the Framework Document suggests "where an investment is primarily to support economic growth, the Company will ensure that it does not do significant harm against its climate objective."

In amongst the chatter about how we can 'do' infrastructure better, there's now a growing consensus that we need to improve the way we design our interventions - 'design' in the broader sense of the word, rather than the narrow sense we tend to use as engineers.
My front-end principles for better infrastructure
Over the course of my career, the following front-end principles have served well to ensure we think through, before we rush in where angels fear to tread.
Be clear about the purpose and the expected outcomes, and engage communities in decision-making through an effective communication strategy.
Prioritise the user, aiming to offer services that are modern, effective and affordable.
Seek to improve people's quality of life and support the transition to a more sustainable future, while also facilitating the functioning of the economy, enhancing productivity and accommodating growth (to the extent possible, given other competing objectives).
Extract greatest value from existing infrastructure through timely maintenance, repurposing, renewal and upgrading. Seek to remove constraints and bottlenecks.
Aim to make best use of data, automation, innovation and technology (including for future asset management), recognising the complexity and risks this may introduce.
Recognise, analyse, mitigate and manage technical, environmental and climate risks, and complete any surveys necessary to support this.
Improve governance, with robust, timely and transparent decision-making, supported by strong evidence-based planning, clear prioritisation, and best practice technical design and delivery.
Seek an appropriate funding balance between 'user pays' and general taxation which incentivises behaviours in the best long-term social, economic and environmental interests.
Complete well-evidenced business cases and risk assessments of proposed initiatives before embarking on projects, including financing proposals. Aim to allocate the risks identified to those best able to carry them.
Facilitate collaboration between the government and business to promote delivery of the broader social, economic and environmental benefits.
Clearly, there are many other issues to consider as a project develops, and the above principles may seem obvious to some, and a counsel of perfection to others, but it's surprising how many are overlooked in the rush to build.

Every five years, in the approach to the Welsh Parliament /Senedd Cymru elections, I put together a Manifesto for ICE Wales Cymru outlining our recommendations for the future with the aim of influencing the new ‘order’ and achieving what we consider to be important goals. This year our report is making three main recommendations in the areas of Resilience, Skills and an Infrastructure Pipeline.
