Do You Think This Car I'm Buying Could Cause Hearing Loss Through Bone Conduction?

Sweetpeach, how much have you given out of curiosity?

Sean · Oct 8, 2014

Sweetpeach - I have made more donations to charity than most of the people I have come across in life.
If I have given 10 bucks or 10,000 bucks ..frankly none of your business z

Why would you buy this car knowing and worrying about how loud it is???

If this is just a car you will drive occasionally, I wouldn't worry about it. If it's a daily driver and you expect to put a lot of miles on it, you may consider something quieter to give you peace of mind.

There are lots of fun high end cars that aren't as loud. Here one list of 30 quietest cars.

I expect by Spring I will be driving a '69 mustang with a 351w and flowmasters. It won't be a quiet car, but I won't drive it too often either.

69 mustang ..nice !!

Tinnitus should be measured in sones! - not dB.

How the test was performed

View attachment 3453
Product Manager Krestian Møller Pedersen (left) and Application Engineer Nick Prgomelja (right) from Bruel & Kjær
The tests were carried out by German magazine AUTO BILD in cooperation with Brüel & Kjær. As part of their luggage, the two engineers had brought with them the latest measuring equipment, specially designed for use in passenger cars. The Head And Torso Simulator (HATS) is placed in the front (or rear) of the vehicle, and picks up noises via microphones inside its head. In addition, a binaural headset was used, allowing one of the engineers to listen to the recordings. Both systems were connected via WLAN to a tablet PC, making it easy to monitor the measurements during the test drive. A prerequisite for an accurate measurement is the avoidance of unnecessary noise, so loose objects such as pens or key chains were not allowed in the test car. Each test run was carried out on the AUTO BILD test track in Bremerhaven by a test driver and an engineer.

This is how the points were awarded
Measurements were accurately taken of where noise was generated and whether it disturbed the quiet atmosphere in the car
The conclusion was the combined results of seven test events of different weighting. The inner sound (front of car) was measured for all candidates. In the case of constant speed driving, the average value of the results at speeds of 50, 100 and 130 km/h were evaluated. In the case of the zero to 100 km/h acceleration, the highest measurable value (peak) was evaluated. AUTO BILD determined the top speed results on the autobahn (German motorway). Speech intelligibility was judged on how well passengers managed to understand each other on the autobahn at a speed of 130 km/h. For many participants, this was not a problem. In fact, the only time a conversation was virtually impossible at high speeds was during the extremely noisy VW Beetle test drives. While measuring the auditory perception parameters, the subjective noise perceived for the 14 candidates throughout the entire test was assessed. Here, sound quality was the most important parameter. In the end, AUTO BILD preferred the V8 sound range of the Bentley to the V12 whisper of the Rolls Royce.
The result

The car’s measurement results were tracked during the test drives using the Sonoscout™ iPad® app
Precision microphones, sophisticated measuring software and attentive tester ears hear everything. Or too little, as in the case of the winner – the Mercedes S 500. The limousine marks the lower end of the current noise threshold when driving – it was even quieter than the Rolls Royce. The electric cars showed that a silent motor alone is no guarantee for in-car comfort – noise is also generated by wind and tyres.

How sound is measured

View attachment 3455
Sound is pressure fluctuations that are perceived by our ears. A microphone converts pressure fluctuations into an electrical signal. Unwanted sound is called noise.
Decibels, dB
The strength of a sound or noise is measured in decibels (dB). The threshold of hearing is 0 dB, whispering 20 dB and a normal conversation around 50 dB.

A-weighting, dB(A)
In addition to the strength of a sound, a human ear also perceives different tones, or pitches, differently. That is why the evaluation of sound is done using a weighting filter. The most common is the A-weighting filter, which mimics the response of the human ear and the sound is then expressed in dB(A).

Sone
There are certain sound pitches that we perceive as more disturbing than others. In addition, we react in a more sensitive way when the sound strength is lower. The evaluation in sones connects the subjective human perception of sound with the sound pressure, which can be measured by our instruments. In acoustics, the sone is the unit of perceived loudness.One sone corresponds to 40 phon, which is the same as 40 dB(A) at 1000 Hz. Two sones are 50 phon and correspond to a doubling of the strength of the sound.

Thanks !

This isn't about what Sean gives to charity...it's a simple convo about what car to buy and noise levels. Holly f@@k!!!

Who is anyone to say what he does with his $$$$$? Maybe a different thread/topic.

Buy the car and listen to a nice music to mask your T. All set . 1 2 3 and 60 miles in 3 seconds...GO !!!!

Buy the Maserati, go for it. I am buying a car here, too. I am going for the Renault Clio, model year 1999 with 1.4 petrol beast under the hood giving enormous 75hp. Naturally aspirated.. ha ha.
Winter is coming so i cant ride my scooter anymore.
