Acoustical Consultant NYC

Acoustic consultant and acoustic engineering for New York City noise problems.

Acoustic Consultant NYC: Testing, Design and Build

Most noise problems in New York are solved twice: once by someone who guessed, and then by someone who measured. Hush is an acoustical consultant and a licensed soundproofing contractor in a single firm. That is rarer than it should be among acoustic consultants and soundproofing companies in the city, and it means the person who diagnoses your noise is accountable for fixing it. As a result, we serve apartments, brownstones, offices and commercial spaces across the five boroughs from our base in Brooklyn.

What an Acoustic Consultant Does

An acoustical consultant identifies what the noise is, where it travels, and what will stop it, and puts numbers on all three. For example, for a homeowner that means knowing whether the problem is the wall, the ceiling or the window before any money is spent. Meanwhile, for a developer or architect it means assemblies that meet code and board requirements the first time. Similarly, for a building in a dispute it means a measured report rather than two opinions.

Our consulting covers:

Noise diagnosis. Airborne, impact, structure-borne or low-frequency, and the dominant transmission path including flanking routes that are not obvious from the room you hear it in.
Acoustic testing and sound insulation testing. Field measurements of sound insulation between spaces (ASTC, AIIC, NISR), reverberation time (RT60), and background noise levels, to ASTM methods. On site, STC testing gives a field ASTC, not a lab STC.
Acoustic reports. Written findings with measurements, photographs and recommendations, suitable for co-op and condo boards, landlords, buyers’ due diligence, and legal proceedings. See acoustic report.
Acoustic design. NYC acoustic design by an acoustical engineer: assembly specifications for walls, ceilings, floors, doors and windows with target STC and IIC ratings; room acoustics design for offices, studios, restaurants, theatres and performance spaces.
Code and board documentation. IBC and NYC Building Code sound transmission requirements, NYC DEP noise guidance, alteration-agreement IIC and 80% carpet rules, and the submittals boards ask for.
Pre-purchase acoustic inspection. Measuring a unit before you buy it, so a thin party wall or a loud mechanical room is a negotiating point rather than a surprise. See pre-purchase acoustic inspection.

Architectural Acoustics and Architectural Insulation

All of this is architectural acoustics, the study of how buildings handle sound. It has two halves. Architectural insulation covers how walls, floors and ceilings block airborne and structure-borne sound. Room acoustics covers how sound behaves inside a space.

On larger projects, in-situ performance can be predicted with ISO 12354, the international method that adds up flanking at every junction. Statistical energy analysis goes further and models how vibration energy flows between connected walls, floors and cavities.

What an Acoustic Consultant Designs, Surface by Surface

Room Acoustics and Office Assessments

Absorption, diffusion and RT60 targets for offices, conference rooms, restaurants, schools, houses of worship and studios. See acoustic panels.

Good acoustical design starts with reverberation time (RT60), the time sound takes to decay by 60 dB after it stops. A long RT60 lowers speech intelligibility, which STI (Speech Transmission Index) and C50 clarity measure. For open offices, Articulation Class (AC, ASTM E1110) rates how well ceilings and screens protect speech privacy.

Mechanical Noise

HVAC, elevator and pump vibration, and the isolation that stops it reaching occupied rooms. See mechanical noise.

Mechanical noise needs the right numbers. A-weighted readings (dBA) under-read bass, so hum shows up better in dBC and in octave bands such as 63 Hz and 125 Hz. NC or RC curves then set how quiet HVAC must be in each room. Also, a tonal hum at one frequency annoys more than broadband noise at the same level.

Ceilings

Impact and vibration paths from the floor above, isolation clip systems, resilient channel and damping compounds such as Green Glue, and the height trade-offs. See ceiling soundproofing.

Walls

First comes construction and material assessment, then decoupling strategy and target STC. Most NYC party walls start near STC 33; however, we design to 55-60+. See wall soundproofing.

Lab and field numbers differ, too. Lab STC comes from ASTM E90. Field ASTC (ASTM E336) usually lands several points lower because of flanking and workmanship. International specs use ISO equivalents instead, such as Rw and R’w, with field tests under ISO 16283.

Floors

For floors, we specify acoustic underlayments, floating floors, mass loaded vinyl where appropriate, and IIC targets that satisfy alteration agreements. See floor soundproofing.

Doors and Windows

Here we specify automatic door seals and gaskets, STC-rated doors, window inserts and specialised glazing. See door and window soundproofing.

Acoustic Consultant and Soundproofing Contractor in One Firm

Many acoustic and noise control engineering practices write a specification and leave. Meanwhile, many soundproofing contractors build what the homeowner asks for without measuring. Hush, however, does both halves, and the gap between them is where most projects go wrong.

Because we are a licensed, insured NYC contractor with our own crews, the assembly we specify is the assembly we install, and the result we predict is one we verify after the work. Also, clients who want design only, or a second opinion on another contractor’s proposal, can hire us for the consulting alone.

How a Consultation Works

Book. A virtual consultation is $250; an on-site residential visit is $500. We credit either fee toward the project if you proceed with Hush.
Listen and measure. On site we listen at the times the noise happens where possible, measure, and trace flanking paths through adjacent surfaces, ducts and penetrations.
Diagnose. Then you get a clear statement of what the noise is and which surface is carrying it, in plain language and in numbers.
Recommend. A scope with target ratings, assembly details, expected results, and a price. Where the honest answer is that a cheap fix will not work, or that bass from a bar below cannot be fully stopped, we say so before you spend.
Build and verify. If you proceed, our crews build it and we measure again.

Field testing to ASTM methods relies on a Class 1 sound level meter (IEC 61672-1), checked against a field calibrator. Readings split into octave or one-third-octave bands, so the weak frequencies show up clearly. Airborne tests use an omnidirectional dodecahedron loudspeaker. Impact tests use a standard tapping machine. Room acoustics tests, by contrast, capture the impulse response, often with an exponential sine sweep. Angelo Farina introduced that test signal in 2000, and it rises well above background noise.

Who Hires an Acoustical Consultant in New York

Apartment owners and renters who want to know what will work before hiring anyone, or who need a report for a board or a landlord.

Co-op and condo boards that need an independent measurement of a complaint, or a specification for a building-wide standard.

Architects, developers and general contractors who need assemblies that meet IBC Section 1206 and NYC code, panel and material submittals with NRC and fire-test documentation, and a consultant who can also install.

Commercial tenants in offices, restaurants, bars, gyms, hotels, schools and medical spaces, where speech privacy, reverberation or a lease noise clause is the issue. See commercial soundproofing.

Buyers and brokers, similarly, who want a unit measured before they sign a contract.

Attorneys and managing agents, finally, who need defensible measurements in a dispute.

Soundproofing Contractors NYC: What to Look For

If you are searching for a soundproofing company near me, soundproofing contractors near me or a soundproof contractor in New York, you will find a mix of acoustic contractors, general contractors and material installers all offering soundproofing services. However, professional soundproofing is a design-and-installation discipline, so ask each soundproofing company NYC candidate:

Will you measure before and after, or is the proposal based on a walk-through?
What STC or IIC do you expect, and how do you know?
Have you checked flanking paths, or only the surface I pointed at?
Are you licensed and insured in New York City, and will you handle the board submission?
Who is accountable if the result falls short of the number you quoted?

The best soundproofing company for your project is the one that answers these questions with numbers. A soundproofing contractor who cannot answer the first two is selling materials. In contrast, we answer all five in writing.

Soundproofing Cost Per Square Foot and Per Room

We price soundproofing by assembly, not by square foot, because the noise type, the performance target and the building conditions drive cost more than area does. Typical Hush ranges: walls $12,000 to $25,000 per room (100 sq ft and up), ceilings $18,000 to $36,000 per room (150 sq ft and up), door seal packages $1,440 per door, acoustic panel rooms $5,000 to $30,000, and floors, windows and reports quoted per project. Our soundproofing cost guide explains what moves the price.

Acoustic Consultant FAQ

What is the difference between an acoustical consultant and a soundproofing contractor?

A consultant diagnoses and designs; a contractor, by contrast, builds. Hush is both, so the diagnosis and the result are the same firm’s responsibility.

Do I need an acoustic consultant for a single wall?

You do need the diagnosis, though. If the noise is actually coming through the ceiling or the door, a soundproofed wall changes nothing. We credit the consultation fee to the project, so the measurement costs you nothing if you proceed.

What is an acoustic report and when do I need one?

In short, it is a written document of measurements and findings. For instance, boards, landlords, buyers and attorneys ask for them; so do homeowners who want certainty before a large project.

Do you do acoustic design for new construction and renovations?

Yes, and that includes assembly specifications, code compliance and submittals, as well as coordination with the architect and GC.

How much does an acoustic consultation cost?

$250 virtual, $500 on-site residential, credited toward the project. However, we quote commercial and multi-unit assessments by scope.

Do you work outside Manhattan? Is there an acoustic consultant near me in the outer boroughs?

Yes: Brooklyn (where we are based), Queens, the Bronx and Staten Island. Our own crews also handle soundproofing installation in all five.

Is an acoustics consultant the same as an acoustical engineer?

In practice the terms overlap, because both describe the same discipline. A noise consultant does similar work, usually focused on noise control. Our consultants design assemblies and room acoustics and measure to ASTM standards; the distinction that matters is whether the person is also accountable for the build.

Can you review another contractor’s proposal?

Yes. In fact, a second-opinion consultation is one of the most common ways clients first work with us.
