[ Materials ] hand , projects the slightest vibrations and modulations into the instrument more faithfully and with less effort , giving the musician greater control . Though the softened warm tone of brass is often desirable , stainless steel produces crisper sounds that suit different kinds of music . Precision Type 316 stainless steel mouthpieces offer the hardest and densest surface available . CNC ( computer numerically controlled ) machined cup and edge profiles can be adapted to the musician ’ s lip and even dental morphology . This level of customization allows for increased comfort and possibilities for experimentation with playing styles . Some players also suffer from allergic reactions to brass . Stainless steel offers an alternative and is relatively inert . Equally interesting are saxophone mouthpieces . Often made of wood , ebonite ( a hard rubber ) or plastic , these pieces also benefit from the properties of stainless steel . The 2 % molybdenum in Type 316 stainless steel helps resist corrosion , which prevents deterioration and changes in playing characteristics . Stainless steel ’ s hardness also allows for an ultra-fast response time needed to realize the full richness of the saxophone ’ s overtones . Mouthpieces made with stainless steel also eliminate the need for surface plating , an important benefit for those who are sensitive to nickel plating .

Sports referees use whistles that resound between 100 – 120 decibels , louder than a chainsaw !
A strong warning with a small whistle ! Less melodious than the music of the brass instruments , whistles resound in much more particular conditions . For example , in sports meetings where the referee ’ s whistle overtakes the clamours of a fevered stadium ! Decibels , a measure of volume , are also crucial when signalling
Training whistles often require a material that resists severe conditions of use , for example , prolonged exposure to water or humidity .
an emergency or distress situation outdoors . A signal must reach 120 decibels to be heard several kilometres away , such as from a boat or the middle of the wilderness . In the more peaceful context of training animals like dogs or birds , the ability to modulate pitch is key . Unlike regular whistles , often made of plastic or light metal , training whistles have specialized shapes that allow for a powerful sound easily controlled by the user . This power and modulation allows a hunter or farmer to recall their animal from kilometres away . Some professional dog-training whistles have the capacity to produce sounds at frequencies too high for humans to hear , blowing a seemingly silent whisper that can be heard by a dog or cat a field away ! These training whistles often require a material that resists severe conditions of use , for example , prolonged exposure to water or humidity . Such models use Type 316 , or more commonly , Type 440 stainless steel containing up to 0.75 % of molybdenum . Type 440 is a martensitic grade whose hardness favours a good projection of sound , guarantees the solidity of the whistle , and protects against mild corrosion .
