1INTRODUCTION
The SV 104 instrument is a revolutionary new approach to occupational health and safety noise
monitoring offering voice comments, audio events recording and vibration shock detection functions
which are new and useful concepts in an instrument of this size. It is a cable-free dosimeter and is typically
attached to the user’s shoulder, close to the ear using the mounting clips supplied.
This personal dosimeter has an incredibly robust 1/2" MEMS microphone (part number SV 27)
enabling easy and automatic calibration using most commonly available acoustic calibrators.
The class beating, high resolution, amazing colour OLED screen displays information in both text and
graphical form and offers excellent visibility in dark sites as well as in full daylight conditions. This makes
taking noise measurement a real pleasure.
Three independent acoustic profiles allow parallel measurements with separately defined filters
and RMS detector time constants. Each profile provides an extensive number of results (like Leq, Lmax,
Lmin, Lpeak, L, LE,…). All required weighting filters (A, C, Z) can be calculated in parallel.
For instance, it is trivial to set one profile to monitor noise parameters using the ACGIH (American
Conference of Governmental Industrial Hygienists) preset, second profile set to OSHA HC (Occupational
Safety and Health Administration - Hearing Conversation) preset and simultaneously monitor noise with the
OSHA PEL (Occupational Safety and Health Administration –Permissible Exposure Level) settings.
Using the computational power of its digital signal processor the SV 104 instrument can
simultaneously measure the dosimeter results and perform real time 1/1 Octave analysis including the
calculations of the statistical levels.
An inbuilt tri-axial accelerometer for vibration shock detection firmly places SV 104 as both the most
technically advanced and the most robust personal dosimeter out there.
Advanced time history logging for each profile provides safe and complete information about
measured signal in the internal large 8GB memory.
The instrument is powered from internal new generation Ni-MH rechargeable batteries offering circa
40 hours1of continuous operation. This new cell technology offers up to 1800 charge cycles in comparison
to standard maximum 500 cycles. Low battery self-discharge is about 3% per month in comparison to 40%
per month in standard NiMH technology. The powering and charging of the instrument from the USB
interface is provided which also enables easy data exchange connection between the SV 104 and a PC
without the requirement of a special docking station.
The instrument works with Svantek’s specialist health and safety software package - Supervisor,
and also with the full analysis package SVAN PC++.
Robust and lightweight design including innovative magnetic mounted windshield enhances
the exceptional features of this new generation instrument. Add to it the automatic calibration feature and
one can say: “Never before has a noise dosimeter been so accomplished yet so affordable, making your
measurements more accurate and reliable than ever before”.
To get started quickly with the SV 104, the first part of the manual describes basic noise dosimetry
information followed by a guide to setting up the dosimeter and running measurements.

1.1 Sound pressure
The human ear responds to audible sound pressure levels in the range from 20 μPa (hearing
threshold) to 20 Pa (pain threshold), resulting in the enormous scale 1:10,000,000. Since using such a large
arithmetic scale is not practical, a logarithmic scale in decibels (dB) was introduced which is also in
agreement with physiological and psychological hearing sensations. Therefore it is common that sound
pressure is measured in decibels. Below there is sample information about expected sound levels for
different sources.

1.2 Dosimetry
Noise is definitely a serious hazard in many workplaces. In case exposure to noise from machinery
processes and equipment is not correctly eliminated or controlled, it may cause permanent hearing loss
in workers. The, so called, inner ear is very fragile part of our hearing sense, which with current knowledge
in medicine, cannot be truly repaired. Therefore it is of great importance to protect our senses from
excessive noise. Exposure to high levels of noise may also create physical and psychological stress, reduce
productivity and interfere with normal communications. This may lead to accidents and injuries by making it
difficult to hear moving equipment, other workers, and warning signals. Undoubtedly hearing loss has a very
significant impact on the quality of life for many workers and their families.
Therefore measuring noise exposure in the workplace is fundamental part of all good hearing
conservation and noise reduction programs. The aim of taking a measurement with a noise dosimeter is to
evaluate the average exposure of employees to noise during a normal shift. Wherever the worker goes the
noise dosimeter goes too so that it captures all of the harmful noise during the typical day.
The dosimeter may be worn for the complete shift if the work pattern is so variable that it is difficult to
predict exactly what will occur or it may be worn for a shorter but representative period and then the full day’s
dose extrapolated from that sample.

SV 104 USER'S MANUAL_DRAFT_______________________________________________

1.3 Standards
The effects of high sound exposure on hearing have been studied for many years. As far back in 1954
AIHA (American Industrial Hygiene Association) –Rosenwinkel & Stewart –described a “new device which
integrates sound energy over finite time periods.”In 1956 –von Witternand & von Gierke obtained a patent
for a noise exposure meter for “indicating the total time that noise exceeded a certain predetermined levels.”
Since then, measurements could be conducted over long periods of time and the instrument was worn by
personnel under normal work conditions.
Finally, organizations developed standards to regulate personal noise exposure. International
standards are specified by health and safety regulations such as the European Union Parliament and
Council Directive 2003/10/EC of February 6, 2003 on minimum health and safety requirements regarding the
exposure of workers to the risks arising from physical agents (noise) or International Electrotechnical
Commission IEC-61252 guidelines. The EU directive links to the ISO 9612-2009 Acoustics –Determination
of occupational noise exposure –Engineering method.
In the United States, the Occupational Safety and Health Administration (OSHA) 29 Code of Federal
Regulations (CFR) 1910 General Industry Regulations: Standard No. 1910.95 Occupational noise exposure,
the Mine Safety and Health Administration (MSHA), and the American Conference of Governmental
Industrial Hygienists (ACGIH) have created slightly different regulations and limitations on tolerable noise
exposure. Noise requirements are to ensure that the hazards associated with the exposure of workers to
noise are eliminated or properly controlled.

1.4 Applications
The SV 104 noise dosimeter is extremely well suited to ISO, OSHA, ACGIH, MSHA, NIOSH,
workplace noise measurements in noise exposure assessments. The dosimeter comes with pre-defined
setups that suit different measurement requirements and offer versatile possibilities to be specifically
configured by the user for special requirements if needed:
- Measurement and control of the industrial noise
- work site assessments
- sites/plants/facilities survey monitoring systems
- hearing conservation compliance
- transportation noise studies
- personal noise verifications
- peak dosimeter for example in military applications
One of the most desirable SV104 feature is the unique data logging function that stores significant
number of noise parameters at regular intervals and superimposed random vibration shock or audio events
during a run.
Noise profiled results can be easily transferred to the Supervisor or SvanPC+ software packages.
The noisiest times can be immediately seen in the graphical report and actions directed to the appropriate
area. This makes checking for different regulatory bodies’ compliance and ensuring if hearing conservation
programs are needed definitely easier than ever before. The SV 104 answers all the important questions
such as WHEN? and HOW? did the noise exposure appear? The data logging measurements can be started
immediately or they can be pre-programmed in advance so that measurement run can begin and end
automatically at a preset start and end time without the need for any onsite supervision.
Additionally the SV 104 allows for custom voice note comments to be added before or after
the measurement run, and therefore this is the ideal instrument for the professional occupational hygienist to
use for all noise exposure studies.

SV 104 USER'S MANUAL_DRAFT_______________________________________________

1.5 Measurement procedures
Preferably, when taking measurements, the noise dosimeter should be attached to the employee at
the start of a shift and collected at the end of the whole shift. In case a shorter period is sampled then care
should be taken to ensure that the result is representative of the full shift exposure. Shorter sampled periods
require that the sampler has a deep and full understanding of the expected working tasks during the shift and
the duration cycles of those tasks.
Before performing any noise measurements, ensure that employees selected for evaluation are
operating equipment or performing tasks under normal (representative) conditions, and emphasise the
importance of continuing to work in their usual manner (wearing the dosimeter should not interfere with
normal duties). Explain the purpose and procedures of sampling to the employee who will be wearing the
dosimeter and the importance of not touching, tapping or interfering with the microphone. Instruct the
employee not to remove the dosimeter unless absolutely necessary.
The general procedure for taking measurements could be as follows:
1. Check that the indicated instrument battery life is at least twice the time required for the
measuring period
2. Check the instrument setup mode is appropriate and change if necessary
3. Check the calibration of the instrument and adjust the settings if required
4. Secure the instrument onto the shoulder of the employee selected for sampling. Refer to the
chapter with specific requirements regarding orientation of the microphone
5. Start the recording session manually if it is not programmed for an automatic timed start
6. At the end of the measurement period, stop the recording session, and remove the dosimeter
from the employee
7. Recheck the dosimeter’s calibration. If the instrument is not within the calibration limits then
the results are invalid (usually if a discrepancy is found between two successive checks of
more than ± 0.5dB in the reference level, then the results of the measurements taken between
the two checks should be considered invalid and the cause investigated and the measurement
repeated).
8. Follow your organisation’s specific procedure for personal noise exposure recordings analysis
9. Ensure the report is submitted to the appropriate person
10. Distribute copies of noise exposure recordings to test participants, explain the results and
ensure that their hearing protection adequately protects against the recorded noise exposure
levels.

3.3 The windshield
During use, it is strongly recommended that the SV104 is fitted with the supplied SA 122 windshield.
To calibrate the dosimeter it is necessary to remove the windshield to gain access to the microphone. It is
not necessary to remove the windshield to record the voice note comments.
The SV 104 uses an innovative windshield magnetic technique to fit tightly onto the microphone

3.7 Manual control of the instrument
Although the Instrument is small, its keypad is designed to be minimal, but still highly ergonomic
and easy to use providing effective operational capabilities. Thanks to that, the number of the control push-
buttons of the instrument is reduced to only three.
Generally the user can operate the instrument by:
- change the VIEW2mode with the <ENTER> key
- select the required ACOUSTIC PROFILE3with the <PROFILE> key
- and SCROLL thru the results with the <SCROLL> key
Notice: To save power consumption and extend battery life SV 104 will automatically switch off
the display after 30 seconds if no button on the keypad is pressed. The LED indicator will still inform the user
about the current state of operation and any possible alarm conditions. Press any key, to reactivate the
display.
