Written online course · No video · Instant access
The acoustics course for people with no technical background: 8 modules, 7 professional Excel calculators and 2 reference manuals. From the noisy neighbour to the home studio, from the humming office to the machine that shakes the building — explained like a friend would, calculated like an engineer.
If you recognise your case here, this course was written for you.
The problem isn't you. Sound is invisible, and anything invisible fills up with myths: egg cartons, "acoustic" paint, a hedge as a noise barrier. This course replaces the myths with physics — told in your language.
Four concrete capabilities, in this order.
Tell whether it's sound insulation, room treatment, vibration or outdoor propagation. Four different conditions with four different cures.
How much a wall actually blocks, how much absorption your room needs, which mount your machine requires, how much noise reaches the neighbour's façade — with the calculators included.
Read a datasheet, tell absorption from insulation, ask for the right figure (is that Rw from the lab or from site?) and spot when you're being sold smoke.
In the right order and at the right cost — from sealing a gap to specifying a double wall or a floating floor.
This course gives you real judgement and real calculation tools. What it does not replace is a certified measurement with class 1 instrumentation, or the detailed design of a large project or a legal dispute. That's what consultants are for — the difference is that you'll arrive at that table understanding every word and knowing exactly what to ask for.
The complete package, with instant access and no expiry date.
The full arc of sound: how it is born, how it travels, how your brain perceives it, how it is measured professionally and how it is controlled — in the room, in the wall, in the machine and in the city. With real cases, myths judged with numbers, worked exercises step by step and the "Translated for non-acousticians" block that turns every formula into a sentence you won't forget.
Not toy templates: consultant-grade calculation sheets, redesigned so a beginner can use them. Adding decibels, reverberation time by bands, bass traps and diffusers, insulation curves from the material properties, composite insulation, flanking, anti-vibration mounts and acoustic barriers. Every sheet ships with a real worked example already loaded.
The course's second floor: every concept with its formal definition, complete formula, limits of validity and a commented bibliography of the books and papers professionals actually use.
The guide to all 7 calculators: which cell to edit, which result to read, the colour code, and a troubleshooting kit.
There are no recorded lessons and no hours of playback. The whole course is documents you read and calculation sheets you use: you open them, search them by word, print them, annotate them and keep them forever. Producing video makes a course more expensive without making it more useful for what you actually need — to understand and to calculate. That saving is in the price.
The travelling wave, masking, the axial room mode that booms, the Sabine decay, the mass-spring-mass system and the diffraction bending around a barrier — in motion, downloadable alongside the module that explains them. Invisible sound clicks when you finally see it.

"I've spent more than 14 years watching people spend money on solutions that physics had already ruled out. This course exists so that never happens to you again."
One-time payment, full access with no expiry date, updates to the material included.
The price is set in US dollars. If you buy from another country, Hotmart will show you the equivalent in your local currency at its own conversion rate, and may offer instalments.
Put it in perspective: a single hour of acoustic consultancy costs more than this entire course. One avoided mistake — the foam that wasn't the answer, the window that wasn't the problem, the "miracle panel" — pays for it several times over.

The ones we get most before people buy.
No. Every concept arrives first as an everyday analogy, then as a definition, and only at the end as a formula — and the formula is already programmed into the calculators. If you can use Excel at a basic level, you have everything you need.
It is a 100 % document-based course: there is no video and there are no recorded lessons. You get 8 modules as high-quality PDFs —readable on any device, searchable by word and yours forever—, 7 Excel calculators that also work in LibreOffice and Google Sheets with no macros, 2 reference manuals and 6 GIF animations that come with the modules where movement explains better than a still figure. If you are looking for a course with recorded video lessons, this is not one.
Full access from day one with no expiry date, including updates to the material.
That's the number one case in the course. The sound insulation and building vibration modules are built around it — including why foam wasn't the answer and what is, with relative costs.
Yes: the full room treatment module (reverberation, modes, bass traps, diffusers, DIY builds with ready-to-cut dimensions) plus the insulation module, so your mix doesn't leak out and the neighbour's motorbike doesn't leak in.
For understanding, diagnosing and solving what you can solve yourself: yes. For certified measurements, legal disputes or large projects: no — but you'll hire knowing what to ask for, what to demand and what it should cost. That judgement is worth money too.
