Kramer Schalltechnik

What Kramer Schalltechnik does

Kramer Schalltechnik GmbH is a privately held German engineering office headquartered in Sankt Augustin that delivers accredited sound insulation and noise measurement services to B2B clients across multiple regulated domains. The company serves six primary customer segments — government and municipalities, industrial and commercial enterprises, event organizers and venues, industrial employers requiring workplace noise assessments, acoustic and environmental consulting firms, and construction and real estate developers — with thirteen specialized service lines spanning building acoustics, construction noise, urban development planning, sound engineering, leisure/event noise, industrial noise, workplace noise, noise reduction planning, room acoustics, sports noise, and traffic noise.

The firm combines proprietary software (MAPANDGIS for GIS-integrated outdoor noise calculation, SAR-NP for VDI 3760 industrial hall sound propagation, and MessKataster for location-based measurement recording) with specialized hardware, including an in-house mobile real-time noise monitoring system for events and acoustic camera capability for sound source localization. Multiple regulatory designations — DAkkS accreditation, VMPA recognition, §29b BImSchG measurement station status, DIN 4109 sound insulation testing center authorization, and Luxembourg Law of 1993 approval — confer legal authority for court-admissible measurement and expert reporting. The 15-person team is led by three managing directors (Jörn Latz, Darius Styra, Ralf Tölke) and includes state-recognized experts for sound and thermal insulation.

Revenue is generated through project-based professional consulting engagements with multi-year contract structures, supplemented by one-time software licensing of the proprietary calculation tools. The go-to-market is sales-led, direct, and relationship-driven, with customer inquiries initiated through the bilingual (German/English) website contact form. The company conducts active research through a collaborative TIFL partnership with TH Köln and TH Mittelhessen on low-frequency leisure noise measurement, publishing at DAGA conferences and in industry media to maintain thought leadership. The company operates from a single office and reports no external funding, subsidiaries, or parent company.

Core offering

Kramer Schalltechnik GmbH is an accredited engineering office that delivers specialized acoustic consulting services spanning 13 service areas including building acoustics, construction noise, industrial and commercial noise, traffic noise, leisure/event noise, workplace noise, room acoustics, and electroacoustics. The firm conducts noise immission forecasts, sound insulation testing per DIN standards, real-time noise monitoring for events, and produces expert reports for regulatory approvals. Alongside consulting, the firm develops and licenses three proprietary software products (MAPANDGIS, SAR-NP, MessKataster) used for noise calculation, sound propagation modeling, and measurement data visualization.

Product overview

Kramer Schalltechnik GmbH is an accredited engineering office for sound insulation and noise measurement based in Sankt Augustin, Germany. The company offers a portfolio of three proprietary software products (MAPANDGIS, SAR-NP, MessKataster) for acoustic calculations, noise mapping, and measurement data management, alongside a comprehensive suite of consulting services covering 13 specialized areas including building acoustics, construction noise, traffic noise, industrial noise, room acoustics, sound engineering, leisure noise monitoring, and sports noise. The software products serve as professional tools for their engineering services, with MAPANDGIS handling outdoor noise calculations using integrated GIS, SAR-NP calculating indoor sound propagation per VDI 3760, and MessKataster managing location-based measurement data visualization.
