Soundproofing spray foam insulation in Olds is mostly work inside houses that have been divided so rooms can be let individually. The person commissioning it is the owner, and the person complaining is not.
The person buying it is not the person hearing it
That sounds like a detail and it is most of the difficulty. An Olds owner letting rooms hears about a noise problem second hand, in one sentence, from somebody who may be describing footsteps, or a television, or a conversation through a wall, or a door. Those are different problems with different answers and only some of them are an insulation problem at all. Before anything is priced it is worth standing in the room that is suffering, at the hour it happens, and working out what is arriving and by which route. That visit costs nothing and it prevents most of the money that gets wasted on this.
Which complaints this can act on, and which it cannot
Noise carried through the air, meaning voices, a television, music, moves through gaps and through light assemblies, and filling a stud cavity with an open cell application makes a genuine difference to it. Noise carried through the structure, meaning footsteps overhead, a door slammed, something dropped on a floor, travels through the timber itself, and insulation in the cavity does comparatively little about it. Hearing that at the start is worth more to an owner than a quote that quietly covers both and only half succeeds.
The partition between two let rooms is the whole job
In a house divided this way the trouble is almost never the exterior wall. It is the partition between two rooms let to two people keeping different hours, and often the floor between an upper room and a lower one. Treating that single assembly properly is worth more than treating the whole house lightly, and it keeps the job small enough to fit into a changeover. Where a partition stops at the ceiling level and the space above it runs on into the next room, that gap is the path, and it matters more than the wall underneath it does.
Why the soft material is the one for this
Open cell is what suits acoustic work. It is light and it stays soft, which is what absorbs sound energy, and it fills the cavity completely so no clear air path is left through the assembly. Closed cell is dense and rigid, and while it is the right product for a great many other things it is the weaker of the two for sound. The foam does not stay exposed either: in an occupied Olds room it needs a thermal barrier over it, which in practice is the drywall going back onto the partition once the cavity is filled, so the finish is part of the job rather than an extra afterwards. More on thermal barrier vs ignition barrier. It is also worth setting the expectation honestly: this work makes a divided Olds house noticeably more livable, and it does not make a wall silent.
